At Gaming XS, we have a rule where you have to have 15 posts before you can play in the arcade, people even complain about that, you guys have to understand that websites/forums can never survive if people do not all contribute to making new threads and posting more. I personally think the 5 posts and hour rule is good, many a time I have seen members spend hours and hours in the arcade playing games and then log out without even making a post.
