Configuration of categories, groups and sub-groups

Hi,

How can I configure the plugin GroupJive such that categories and groups are only created by administrators but still allowing registered users to add contents to groups (upload file, write to the wall, add a new viedo, etc ....)?

If allow registered users to create sub-groups or nested groups (not first-level groups), how to create a menu that lists only groups created by administrators?

Thanks in advance.

Categories:
GJ > Config > Categories > General > Create Access

Groups:
GJ > Config > Groups > General > Create Access

You can't have user specific group lists.
