I want to set up the following situation:

- Channel 1
- Channel 2
- Channel 3

Guests should not be able to create Sub-Channels on Channel 1 & 3 but they should be to create Sub-Channels on Channel 2.

If have tried to remove the create sub-channel permission for Guests Server Group and add the permission to the Channel 2 Permissions. But this dont work for me. It seems that the Server Groups have a higher priority as the Channel Rights.

Which Settings must i change to make this situation?

PS: Sorry for my bad english.
