For example, if it could be used + or - sign for including, or excluding forums instead having | sign.

So we would have something like this:

5+5,3,6,7,8
10-5,3,6,7,8

In this example forum 5 would show 5,3,6,7 and 8 forums and forum 10 would show every other forum. It would be great, and this way everything would be covered, even usergruop permissions we could manually control without problems.
