Its a great idea i just think individual rpg's could get a little cluttered with multiple people trying to discuss multiple rpg's on one board. I have seen elswhere that an actual OOC board sometimes works. Since we dont have that sort of space maybe any RPG that gets over so many posts or pages be allowed to set up an OOC thread here. Lounge should be the quieter of the boards ('should be') and is more of a bulletin board than an active thread setup.
Just a suggestion.
