Please note you will require administrator privileges to perform these actions
Once you have clicked on Administration, click the User Accounts tab.
Click the + Add a User Account button, enter the email address of the user you'd like to set up and click the Save button. This will generate a notification and an alert that the account requires moderation by you, the administrator.
The email address holder will then need to activate their account by the system generated email sent to them.
If you have moderation setup for all new users, you will need to Enable them in order for their access privileges to be fully activated. Anyone who has administrator privileges will get the alert that a new user has been created and is awaiting moderation:
This will take you to User Accounts where you can Enable the new user.
