It sure is! These are our homes there:
Facebook
Twitter
If you have either of those accounts then I'd strongly recommend 'liking' us or 'following' us there, because we post announcements there concerning AFF. So, for example, if the website goes down for whatever reason then it gets posted to those two locations to let you know, as well as when it's back up. And don't worry, we don't post useless rubbish, only stuff that is related to AFF!
Please keep in mind, though, that if you have problems of some kind then there are forums right here to post that, not on Facebook or Twitter.
