Geez. Lots and lots of drama going on with boards nowadays. (But hey, at least the exodus and subsequent wankery over at PFU was over something fairly valid, I think.) In any case, I'm not sure what's going on with Pokecosmo, but to be perfectly honest, I have to say, "Holy crap." Although Oni and I are off and on friends, "You must understand, without me, this forum is finished"? Buh? You just need one competent, active admin to run a forum because then, that competent, active admin will get competent, active staff. That competent, active admin doesn't need to be anyone in particular as long as he's competent and active. But you probably already know this; I'm just responding to Oni's comment here.
(And I totally didn't tl;dr the rest. Man, I need more sleep. Or more time lurking on Cosmo.)
In any case, good luck.
