wish i could help you with BCG but it was that long ago i cant even remember the exact date.
we were a public tracker at about 2003 for over a year. went offline for 6-8 months ish than came back as the PHP private tracker.
but as most know, we have been hacked and all sorts of things have happened since then.
the only definitive date i can give you is
08-12-2006 which is when BCG 2.2 was born, so lets say thats our birthday but we have been around for a lot longer than that.
