To assign a user or user group to a user role, log in as an administrator, go to the Administrative menu, and select Role Management.
On the Roles page, click Edit in the Tasks column of the user role you want to assign users or user groups to.
To assign users or user groups to the user role: Select a user or user group from the Available column and drag the user or user group to the Assigned column. Or, use the < and > arrows after selecting a user to move that user or user group to the Assigned column.
To delete users or user groups from the user role: Drag users or user groups from the Assigned column to the Available column. Or use the < and > arrows to move the user or user group back to the Available column.
To filter the list of users, use the Search boxes at the top of the columns. Type a few characters of the user names you are interested in and the list of users displays only the user names that contain those characters.
