Hi, I need to organize users in groups - but I do not see the concept of groups in omeka??? Is it planned to add groups?
I do not mean roles here- roles are for organizing permissions. I need groups.
I would like to have private groups which can share different areas of the site with each other, but not with other groups - depending on the roles a user has, moderators and admins might see multiple groups, if they are a member of a group.
Thanks for your attention!

There are no plans for adding user groups to Omeka, but that is a feature that could likely be accomplished through a plugin, depending on the feature set and scope.
