Well since post count matters a lot, Why not have a poll to decide which game, as stated above, and only have maybe one or two games going at once. That way people can't spam a bunch of games at once, and if they posting after themselves, an mod can adjust that accordingly. Of course I would put the rules, or whoever makes the thread, that state absolutely not double posting or multiple postings after oneself. I will put up a poll to determine the first game.
Everyone put down your ideas you want for the first word game with some explanation of how it works. I'll wait a little while then put up a poll with the ideas I get.
