I was wondering if there was a way I can use the user groups in K2 to restrict access entirely from various users. Not just the degree of control they have over an item.What I would like to be able to do is have a client section with various work relevant to different clients in different categories.When a user is logged in and goes to that section only the categories assigned to him will be visible.I'm new to both joomla and k2 and initially thought this was something I would have control over with user groups.Thanks in advance....
