I am logged in as testuserx and I can not see Forum X when looking at http://kirbydemos.ath.cx/forum/. I can get to Forum X with the link you provided, but I can not see it in the forum list.
Using IE6.

My Cat A is just for people who are in special usergroups that are different from registered users. Everyone who is in a special usergroup, is also a member of registered users and has access to all public forums.

In addition those who are in a special usergroup should be able to see cat a, and forum x (if they are in usergroup x), but not forum y (because they are not in the usergroup y).

attroll and I were just testing this out on a board he has set up for testing purposes, and we didn't find a good solution to my problem.

Let me try to write this up a little more concise.

I have registered users. The registered users can freely access public areas of my board. Registered users can also be part of any number of additional usergroups.

I currently have 40 private usergroups.
Each usergroup has it's own private forum.
Those 40 private forums are located within a private category.
Registered users who are not part of a private usergroup should not be able to see the private category or private forums. This part is easy, and I have it working without a problem.

Members of a private usergroup should be able to see the private category in the main forum listing (main forum page, whatever you want to call it). Within that private category members of a private usergroup should be able to see the private forum (or fora) they belong to, and nothing more.

So if a user belongs to one private group, then he or she should not be able to see the 39 other groups.

Currently I see two MAJOR problems. Whenever I set a usergroup permission in the category, it is inherited by all fora within that category. That's a great feature, it just sucks that one can't turn it off.

Here is what happens.
I create a new private group, group41, which gets it's own private forum, forum41, under my private category. I do want group41 to see the private category, but only forum41 within it. Instead I end up giving group41 access to all other forums within the private category, because of inherited permissions. So then I need to go through, and manually edit the group41 permissions for the 40 forums group41 doesn't belong in.

There has to be a better way...
