Is there such a mod??

[Rickeo]

Hello am looking for a mod if there is one or if this can already be done by default with vbulletin.

Basically what I want to do is allow users to post in a designated forum that when they post it will allow there username to be completely hidden and only admins or x usergroups can see the username of who has posted.

I already see it working on another forum and I really want this think of it as a confessions mod lol as people can discuss what ever they like but only admins or designated usergroups will be able to see the username of who has posted

So in a way in this particular forum it will kind of hide the whole postbit/postbit_legacy.

If anyone knows of a mod like this please point me in the direction or if anyone would kindly make one or show me how I would be so greatful.

Thanks

Rick
