Gec recently set up a new forum board, Kosmosis, as an attempt at a rebirth of the old Spore roleplaying on Gaming Steve in anticipation of the release of spore. While things are still getting worked out, I'm sure some of the other members of this board may be interested in signing up, and possibly participating in ironing out the rules.

Edit: We've recently moved to a new forum. The old one can be found here
. I've also set up a wiki
for archiving gamingsteve and Kosmosis creatures.
