I think you didn't get what I mean. Suppose that I have 4 forums on my board: 1, 2, 3, and 4. Forum 1 has a moderator called 'A', forum 2 has a moderator called 'B', 3 & 4 have no moderators. Now moderator 'A' can move threads from forum 1 to any other forum. He can move threads to forums 2, 3 & 4. Modarator 'B' also can move threads to forums 1, 3 & 4, but of course he can't move threads from those forums to forum 2.

What I want to do is to exclude forum 4 from the moving permission so the moderators can move threads to any other forum except that forum. So in our example moderator 'A' can move threads to forums 2 & 3 only, and moderator 'B' can move to 1 & 3 only.
