Manage users and groups
Users can be added and managed by navigating to the Administration menu on the navigation bar and selecting User Administration.
Groups can be added and managed by navigating to the Administration menu on the navigation bar and selecting Group Administration. Users can be added to the group in the process of creating the group. At any point in time if you need add/remove members from the group, simply come back to this page and click on the group name. Here you can edit all aspects of the group.
For easy app distribution it is very convenient to use groups, but please note that if you grant the entire group developer rights, you may end up in a situation where all group members are notified about crashes etc.
