This site is powered by Drupal for Facebook.
The page you see here is also visible in a facebook application.
Followed this tutorial here: http://drupal.org/node/685320
Works great, but is there a way to post directly to FB without needing confirmation in the pop-up box?
It can be done, although right now fb_stream.module does not help much. My intention is to add some features to that module. If you're up for it, add them yourself an post a patch to http://drupal.org/project/issues/fb.
To do it... first get the user to approve the publish_stream extendedpermission. Then, use the graph api to post (http://developers.facebook.com/docs/reference/api/post).
If you or anyone else has interest in developing that but needs help, post to the issue queue and I'll help.
