Post counts / Only who create thread!

[skariko]

Hi,
I want to disable the post count only in a determinate sub-forum only for who reply and not for who create the thread.

So I want that who open a new thread have +1 on his post count.. but who reply to that thread don't.

Is it possible?

Thanks,

(edit: it's a sub-forum of Jokes and who make a thread is correct that have +1 post counts.. but all the members that answer "lol" "great jokes!" "ahahah" etc.. is not good that have the +1 post counts, here it is)
