I have a XOOPS 2.2.4 site and cbb 3.01

I want my moderators to have the possibillity to suspend and/or ban a user if necessary.

Situation now : I have to give the moderators admin rights to get in the admin panel on the index page of cbb, there they can suspend a user, but there are two downfalls?
First : the moderators have admin rights so they can also change for instance the complete forum.
Second : the suspension is only for the forum, so the user can login and access other parts of the site.

What I want is a suspension for the whole site, for instance by changing the status of a user from active to non active, and the possibility for moderators to actually ban a user by blocking the ip-adress, without rights (for the moderators) to admin things.

Could this be done?
