- Login to the wiki (you'll need to be a member of the Sysop group)
- Go to Special Pages > Userrights and enter the username of the person to be added (if you're not sure you can also go to Special Pages > User List to see a listing of everyone's that has logged into the site.
- From the Available Groups column select the group the user should be added to.
- Click the Save User Groups button to apply
