In order to make it easier to assign the same rights to different users you can separate them into different groups and than assign specific rights to each group. To create a new group you just click the “Add” button in a “groups” submenu of the “Users” menu, then enter its name and notes if necessary. To add users to the group you just click “Add user” in the same window and select the necessary users from a list. After that you have only to setup rights.
