I'm developing a Joomla 3 website, where registered users can belong to several groups of interests (music, theater, technology, and so on).
I would like to give permission to my client to edit users by placing them in groups he desired. For example: user 1 can be in music and theater group; user 2 just registered (no group) and user 3 in technology group. Unfortunately the only permission that Joomla 3 allows you to edit users is the Administrator, but if I give this permission to my client, he will be able to edit articles, themes and other features that I do not want it to edit.
How can I create an access level that can manage only users list?
Thank you and sorry about my english.
