Sorry, but you're looking in the wrong thread for people. Since Khaotic-con is a pretty new con still I say make a thread over here in "Other":

I'm thinking though that the Admin's might just move this there instead. I'd also search in the "Seeking Cosplayers" thread in this one for Florida convention goers:
http://www.cosplay.com/forumdisplay.php?f=15 and there is another one I'm sure but that is for Florida. On another note, I live in Florida too! Sadly, can't go to KK due to plans for an out of state con in the same month. If I had money, that'd be awesome but can't.
