I want to be able to get the tagged posts for a page (e.g. harvard). what kind of authentication do i need to have (access_token) or do in order to be able to get those posts? they are publicly available.
You answer lies in the link you posted (https://developers.facebook.com/docs/reference/api/page/)
In the connections section, it says "any valid access_token or user access_token":
tagged
The photos, videos, and posts in which the Page has been tagged.
any valid access_token or user access_token
a heterogeneous array of Photo, Video or Post objects.
So if this is incorrect, you can scroll to the bottom of the link and click the Report Bug link to report an error in the documentation.

i want to get comments and sub comments from facebook is it possible through their api or are there any alternatives from where i can do it .
I want the comment , date and if possible location of the user
You cannot get a user's location, but you can get the comment and date/time.
Docs can be found here https://developers.facebook.com/docs/graph-api/reference/v3.3/comment
Access would either require manage_pages and a page token valid for the respective page or Page Public Content Access feature approved.
I can not get Facebook Graph Api to retrieve comments from websites that implements facebook commenting system.
I want to provide sentiment feedback statistics for various websites. I wanted to retrieve comments from few websites which are implementing facebook commenting system, I found graph API method /{object-id}/comments
which should return set of comments from specific object-id (which is an url of article consisting set of facebook comments?). I keep getting json response with ID only or an error with "(#10) To use 'Page Public Content Access', your use of this endpoint must be reviewed and approved by Facebook. To submit this 'Page Public Content Access' feature for review please read our documentation on reviewable features: https://developers.facebook.com/docs/apps/review." message. Any feedback on that?
/{object-id}/comments is for objects on Facebook - posts, comments, videos, etc. An external website that uses the comments plugin, doesn’t fall under that to begin with.
What you want, is this here - https://developers.facebook.com/docs/plugins/faqs#faq_1603507626630008:
Can I get comments for a URL via an API?
The comments for every URL can be accessed via the Graph API. Simply make an HTTP GET request to:
https://graph.facebook.com/v2.6/?fields=og_object{comments}&id=<YOUR_URL>&access_token=<YOUR_TOKEN>
I have a facebook application and want to use it to allow my users to post simple messages on a page.
I used api explorer and made a few api calls to post but all that I post is not visible for other users than the one I am logged with and for not-logged-in users. I want my api-made posts to be visible for everyone, not just for the user that posted them.
I mention that if I make a post using the textbox directly (manually) on the page then those posts are visible to everyone, even for non-logged-in.
Is there a step-by-step tutorial for this?
What I finally want is to allow users of my site to post messages to facebook directly (after login to facebook of course). Posts should be done by different users to different pages as the respective page.
Code samples are much appreciated.
For posting to a page as the page, get a page access token: https://developers.facebook.com/docs/facebook-login/access-tokens/
To post as the page, you need an access token with manage_pages permission. And there’s no build-in way for a page admin to get notified when someone wants to post to their page as the page, because that’s not a common use case. But the page admin can grant you manage_pages once so you get a page access token, and then you can use that in your app to post to the page, you just have to set that access token explicitly when doing so.
I'm using the Graph API to return Facebook posts from all NHL teams. Every team returns the posts fine except for the Montreal Canadiens, which returns no posts. I verified that there are posts on their wall, and that the Facebook ID that I used is correct(see here)
I get back an empty JSON list when I try using this link for the Canadiens:
https://graph.facebook.com/110877132302973/posts?access_token=(my access token)&limit=10
Any help would be appreciated! Thanks.

The posts on that page all have a custom privacy setting - you need to make sure you're attempting to access them using a User access token for a user that meets whatever restrictions they've applied.
App or page access tokens won't be able to see the posts, nor will user tokens for users who don't meet the restrictions
OK, apologies for the verbose title. Let me give the background in a bit more detail.
My website allows my registered users to create new pages, each of which has its own unique URL. Each page has a Facebook "Like" button on it. I've already implemented Facebook Open Graph API meta tags so that the pages are proper open graph objects, and when some other visiting Facebook user "likes" the registered user's page, a post appears on that Facebook user's wall saying they have liked the page. The Facebook Like widget also displays the number of "likes" that page has received as normal. So far, so good.
What I want to do is allow my registered users to be able to communicate back to the Facebook users who have liked their page. The community of "likers" for a page is a potentially valuable social media resource to the registered user, if only they could communicate back.
I am aware of the "admin page" link you get beside the Like button, which can be used to post to these people, but that is not an option for my registered users as they have no privileges in relation to the Like button.
What I want to do, if possible, is setup a form to capture the registered user's message back to the Facebook users, and then my website sends the message on their behalf, without having to ask for any extra privileges from the Facebook users.
The following Facebook documentation pages seem to say this is possible, but having followed the Open Graph API documentation, I can't get it to work as described - http://developers.facebook.com/blog/post/465/ and http://developers.facebook.com/docs/reference/api/ ("Publishing" subsection). I can get the access token correctly in the first request, and plug that into the second request to do the post, but that doesn't seem to do anything and doesn't return any error.
Since it doesn't work for me, I'm wondering if this is possible as described, or do I need to get some sort of extra permission to do this? I've seen reference to offline_access permission but as I'm new to this stuff I am not sure how it would fit in. If I have to get the Facebook users to grant permissions, this is not going to work as envisaged.
Any thoughts would be most helpful.
The short answer: No, You will never been able to post on someones wall as another user.
The long answer:
You could try to ask for offline access but then you are asking the user to hand over all their facebook data and give you access todo whatever you like their accound, so that is not likely to happend.
The next problem is that they have to be friends to be able to post on each others walls.
Thats why Pages was implemented, so that organisations could announce/talk with the people interested.
However if you have created the like button correctly and give the pages correct meta data, you are able to post to user who have liked it.
Scroll down to Publishing:
http://developers.facebook.com/docs/opengraph/
Just add a form for your user and let your system publish to the correct page, you probably will need a offline token from your own account or similar to use on the server.
Another more complex way could be to generate a facebook page for each page you have on your server.
When the user creates a page on your system a page is created on facebook but as your app as admin.
And when another user likes the page they like the facebook page, hence you have the possibility to post in that page and speak to the user who liked it. (whooa thats a mouthfull).
