You can now manage the roles for each user. You can assign new users to roles or remove an existing user from a role. All users are in the Registered Users Role and the Subscribers Role automatically. You can add users to other roles to allow them access to things on the site.
To manage the Roles for a user follow these steps:
Go to Dashboard
Look up the user account
Click on Roles - Here you will see all the roles they are in
Select the Security Role you want to put them in
Uncheck the Send Email box
Click "Add Role to User"
Close
NOTE: If a user has more than 1 account make sure that you are selecting the account they wish to use. Only the account assigned to the role will receive access.
