members must have certain amount of post count to view a certain thread

[influence]

Is there any hack like this out there? I tried using the search feature but I think that thing is broken or some sort.

I have a forum and to my understanding, must people register only to view threads on that forum and ignore the rest of the site.

So I would like to have a hack or code that will force people to have a certain amount of post counts before being able to view or post in threads on that forum. They should still be able to view the threads listing on that particular forum but they can't open the threads there.

Will also be nice if that hack include checking to see that that member post replies on at least 2 to 3 other forums on the site.

Your help is truly appreciated
