As I said my web site was hacked. It currently uses Joomla! as the back end , something few people seem to know. The only feature that I really like is the fact that I can categorize users. So, some users have access to parts of the web site that others don't.
Is there a plug in or other backend that would provide me with this feature? When I look at things like word press they seem to provide templates and little else.

Thanks
