I am trying to set up a solution were only selected groups/people (it is not possible to give only a single person access to a forum, ist it?) have access to a subforum.
The first of such sub forums I was giving admin FULL access and the special group "standard access". This worked.
Now I wanted to set up a second of such forum, created a new secondary group meant for giving very few people (here only 1!) access to a forum and saw that this newly created group got access to the old limited forum. How can I prevent this?
