Can admin post as any user?

[AlexisMedia]

I have a forum that I've sealed off new threads being started in unless it's admin. Is there a way that I can start threads in that forum as any of my users? Through searching I found a mod called "post by proxy" that seemed to allow this but it was only available for vB3 and I need it for vB4. Any other mods or recommendations for this?

If not I'm thinking my only other options is if a users thread is approved for that forum is to have them create the thread and then moderate threads in that forum?

Or move a thread to it?

Basically it's for an award forum though and I'd like to just be able to post a thread as that user without them knowing yet...

Thanks!
