I'd like to moderate the first post of new users.

Hello,

I'd like to setup my forum so that I can moderate the first post by new users. I'd like to do this to weed out the spam we're getting while it not effecting the posts shown to our registered, regular, users.

I was told I can do this by editing some (custom?) usergroups and using promotions, but would like to ask here for some assistance.

Thanks!
