Yeah and if any other message board I've ever seen is anything to go on, not all of these people will necessarily stick around forever. Those that do will become part of "us" - I really don't see what the big deal is.
That said, when registration was opened back up in mid-'00 and a bunch of us annoying newbs started flooding A-S with our faggotry, most of the old-skoolers weren't too pleased with us being there either. Change happens.
