User Permissions (invites, etc)
How can I adjust the settings on the left side of profile pages for certain user groups?
For example, I don't want to show invitations for anyone except for administrators.
Also, I don't want anyone to be able to adjust their who's online settings.
I haven't found a way to do this yet, and I'm not having much luck digging through the various template files. Can someone point me in the right direction?
