[Request] Having to approve first post of a user until further posting

[Kikkerking]

Thank you, it's great so far. However, it's not very optimal yet because of the following reasons and I'd like a little extra plugin for that so it works perfectly.

This is the problem.

If new users join and active their account through email, they get in the Registered usergroup. Now I don't want to have to approve all posts of that group as I already have hundreds of active members in that group. So one solution is a plugin where you can create a new usergroup where people who activate their account go in first. Then when they post I have to approve posts from THAT group and I can move them to the Registered usergroup myself if they're good.

OR, what also could be a solution is that you ONLY have to approve posts from Registered members that are new, that have 0 posts except for that 1st post that has to be approved.

Thanks in advance, I really appreciate it.
