MyBB Community Forums

Hi,

I am looking for a plugin that makes users have to post in a particular forum before they can post in other forums. I want a plugin that directs users to an Introductions forum before they can post in other forums. I am aware one exists but I do not know what it is called.

Also - how do I replace the memberslist with showteam as I want a memberslist sorted by ranks.

Thanks,
Dan
