OK, this is confusing me.

I want to set the groups/ranks

-Site Owner (Me, basically)
-Administrator
-Super Moderator (Moderator for all forums, but can't do everything an admin can, like banning users etc.)
-Moderator

I have set up these ranks in the "ranks" section under "user admin". But now I want to set different permissions for these ranks. Like, I will be the only one who'll be able to create new topics in a certain forum, but all registered users can reply to the topics. Then all admins can create topics in another forum and all registerd users can reply etc.

I figured I'd be able to set this in "permissions" under "forum admin", but all the user groups I can choose from there, are ALL, REG, PRIVATE, MOD and ADMIN. Where are the ranks I created? Can someone help me out here?
