I'd like to learn how to make a private forum for only members of one group

Whenever I make on, others can read and reply. I only want one group to read it.

Like it's top secret.

Could someone help me?

General>Categories and Forums
Click on a forum name
Permissions tab.
Change who can see & who cannot see that forum.

Sir, I tried that already.

I cannot change the permissions of the other groups

If you check it for members, then other groups cannot be unchecked. So you can create a new group called members with 0 posts to autosubscribe to that group.
So that whenever a member registers he automatically is added to that new group members.
Hope you understand what i am saying.

Thank you sir

I understand it now
