hide last post/thread.

[Physiodifis]

how do I hide the last post/thread from certain subforums, from my homepage?

Also, I'd like every thread to appear just once in my home page, even if it has received many answers.

Thanks!

Anyone?

Please, help me in that, it's really urgent.

At least, give me an answer as to how I can stop new posts/threads from appearing to my homepage, that come from certain subforums.
