Minimum of post before members can see treads?

[Solice]

Some part of my forum is not for guest, but just for registered members.
But I see that many register JUST to see this treads...
(and never post anything)

Is there any way to set a minimum of post (maybe 10) before members can see this treads?

I've search my admin cp, but can't find what I'm looking for.. :/

Thanx

Anybody knows?
