To create a Admin, e.g. a committee member, select Organisation > Admin and Roles
If the Contact is already in the Admin list, you can adjust their Admin Rights by selecting Edit Admin Rights and clicking on the appropriate check box item to unlock it - or, give them the permissions for that level.
If the Contact isn't yet a Admin, you can add them and give the appropriate Admin Rights.
Communicate Admin Rights
If a Contact has Communicate Admin Rights, when logged in they will be able to see their Dashboard, Communicate menu and their own Tasks.
A Admin with Communicate Admin Rights can send new Email and Group Messages.
Note: A Admin with Communicate Admin Rights can send to Contacts and Groups but will not have the permissions to view Contact or Member details.
