Good job everyone. I should have limited you on 300, so you all get full credit there. There are many groups that had no founders in other groups.
100 - Finn McCool
200 - 52 known, seems like quite a few more
300 - Griffin, Taurus, Quantum, Jabberwocky, Tottenham, Pharside, Umbongo, Jackals, X-iles, Starsky, Asphodel, Hobgoblen, Java, Polaris, Xhosa, Nemesis, S, KK, QQ, PQ, and Balrog
400 - Whiskers
500 - Marjorie Dawes, DAffyd, Emily Howard, Foxymoron, and Srutny Gippo Vivian.
Good job!
