Question User Groups, User Group Privileges, ACLs

Thanks for the answer

I may not have written clearly enough, but I dont mean how to set for special groups like reistered, author etc, but for my clan from the Community Builder. I want one category in the forum to be only for the clan members from CB. Is this possible?

I think it's possible if you use GroupJive. I don't have any personal experience with using GroupJive. You could ask the question at www.joomlapolis.com

there is a way the have some topics READABLE only for a group of registred users?

Thanks!

You could place those read-only topics into a locked category. Is this what you wanted to know?

but in this way no one will write on it?

I need a way to have a group of user who can read a write a topic and another group who can only read it.

Thanks!

I see your point. Although moderators and administrators have write access, this isn't quite what you want.

At the present time there is no way to have groups of users (who are not moderators or administrators) who can write while other groups of users only have read access. Sorry. That's the way it is. I've merged your topic with another one that discusses these similar issues. It may happen that a future version of Kunena will implement the idea as you have described it.
