Do you guys remember the post about the permissions page check boxes etc looking different on here than on my site https://skhilled.com/cztest/index.php?msg=1253
Well I found out what the issue was. In the settings for permissions 'Forum► Administration Center► Permissions► Settings' there is 'Enable the option to deny permissions'. If I enable that I see the same drop boxes as you do on here, so the problem...not that it really was one...is now solved ;D
Cool!
