New User Requirments

[clam]

Hello, my forum is working on cutting down the amount of jerks getting through and spamming up the place. How can I set the forum that new users have to post in an introduction forum and then a mod has to okay them to have posting access to the rest of the forum? And to have it so that the new users know they must post their first message in the new user threads? Thanks for any help in advance.
