Adding an additional administrator
How do I add another administrator (with full privileges) to a community? I tried using the control panel functions of managing users and saw where I could block someone, but not where I could change their privileges.
This has been implemented. Sorry for not telling you sooner.
From the edit user screen you can add the "site admin" role in the Roles section.
You can find users by clicking on their username anywhere in the system then going to the "Edit" tab on their profile page (as an administrator) or by searching for them on the Administration -> Manage Users screen.
At the moment this is not possible. We are adding user rights management features within the next month. Sorry.
