The abilities of your users are determined by the group(s) they belong to. If you are an admin, you can get an overview of your users' groups by heading to the cog in the top right-hand corner of the page and selecting Users. This page contains information about the group(s) your users belong to.
If you would like to update the group that a particular user belongs to, return to the cog in the top right-hand corner of the page and click 'Groups'. Here you will find a list of all of the groups that currently exist on your site.
Using the Search group users... bar if necessary, hover over the user you wish to remove from the group and click the small delete icon next to their name.
Make sure you hit the 'Save' button at the bottom of your screen before continuing.
Remaining on the group edit page, to add a user to the group, click the 'Add User' button which will allow you to search for the desired user and add them to the group.
When attempting to add a user to a group, keep in mind that the user's profile type must match that of the group. If you are unsure of how to edit a user's profile type, check out our handy guide to performing this action.
Once again, don't forget to hit save once you're finished making changes to the group.
One More Thing
We advise that you only attempt to add or remove 3 users from a group at any one time, to ensure that the changes are saved successfully.
