New User Intro Thread?

[Reycer]

Hey all,
I think someone asked this before, but I couldn't find it. Is there a way to make it to where a person who is a new member, must post in a certain thread before they can post anywhere else? I know that I could assign them to a certain usergroup and then once they make the post, manually move them to the other group, but that's a lot of work. Is there something (like a mod maybe) that could do this automatically?
