Gamers Plaza : This is where users can dicuss new game concepts, large public collaborations or gaming tips. (Note on Regular+ Members can access this page).
RPFG's : This is short for RFPG, Groups, Contests and Games, and this is where you find forum games which revolve around rating the member above you on something etc.
