I am not sure this is a legitimate group... they don't have any admins and only 156 members. I'm sure Indy or another admin (or a mod for that matter) would have let us know about something like this and from my remembering*, has not. If it isn't legitimate, it's copyright infringement. * I am a stoner, so don't hold my word for it.
ive been apart of it...however im going to take this as an opportunity to post my group You're Cute When You're Mad | Facebook People Who Smoke Weed | Facebook the 2nd one might appeal to you stoners more.
Yeah there's something about the anonimity of GC that I quite enjoy. Joining on fb just takes a little bit of that away.
