Hello. I know there is possibility to disable post count on some subforums, but im not familiar with it. Is there any tutorial? 
Also, you were here talking about the same, and suggested to make a buttons for it. What happend to that?

Currently at this time you can't disable post count.

Suggestions are implemented when the techs decide to implement them and this suggestion hasn't been added yet.

Okey, thanks.

Your Welcome
