Hello guys, in my community there is a “presentation” category, and a lot of people say “hello”, and other messages.
So I have an idea:
Is there any chance to config the category section to no count posts by user?
I mean, count topic created, but no for replays.
I remember that phpbb, or others forums platforms had this option.
Why discourse not? 
If you mean “having post activity in a specific category not count toward gaining trust levels” then–

Again here… sorry.
Well, that thread is not solved, that feature is possible?
AFAIK you can use a categories Edit → Settings to turn off
Allow badges to be awarded in this category
That will mean that posts in the category don’t count towards getting any badge that uses posts as a basis for granting badges.
But it will not affect a members post count nor affect their Trust Level.
Thanks.
With this…
Do you mean that in summary (/users/mittineague/summary) the part where shows “n” posts created still counts in that category where turn off “Allow badges to be awarded in this category” ?
Yes.
On old forum boards, they needed this because post count was the most important thing a member could have. People were elitist with those counts and so.
On Discourse badges fill this role, so we enable disabling badges in off topic categories.
