Way to make members introduce themselves before reading or posting?

Is there a way, when users register, to make it so they have to introduce themselves before reading or posting?

Or, is there a way, before activating a new user, to read their profile before activating them (I get their request to be activated via email - but I want to be able to see who they are before activating them).

Thank you.

Well you can make a forum that they have to post in and once they do you have to manually place them into a new group and that group will have access to all forums.

OK...I'm not sure how to go about doing that (setting up a new forum so they know they have to post there first). Would I put some kind of message on the original forum's log in page so they know they have to go to another forum first?

Something like that can only be done with the advanced features of vBulletin
