As a site administrator, you can choose to make certain members of your website 'Moderators' or 'Administrators'.
A moderator can help you manage your site. This will be very useful when you have a large amount of submissions being made, and when you may not have time to deal with them all single-handedly.
To make a regular member a moderator, go to the 'Manage' and then 'Members' section of your Admin panel.
Once inside the 'Manage Members' section, you will see a list showing all your members, any of whom you can make a moderator. To make a member a moderator, find them on the list and then click their box.
Select their role by clicking on the drop-down menu where it says 'Change Member Level'. Once you are happy with your changes, make sure you press the 'Submit' button.
A Moderator will be able to go to the 'Manage Members' section and 'Manage Posts' area within the Admin Center. Another chosen Administrator will have access to all of the Admin Center. The same as the site creator.
