To all the people asking for BCG invites, I hope you know that BCG does not give invites to its members and only to the staff (which means you can forget about getting an invite). BUT, they do purge accounts often and open signups so that's basically your only chance to get in.

samkhan, Welcome to PG! Since your first 2 (and only) posts are asking for an invite, you shouldn't expect anyone to come forward to help just yet. Get acquainted and hang around a bit (at least introduce yourself man!) before expecting anything.
