Can i have two admins and how do i change a mod to admin

I want to change a mod to admin so they can help me out moving forums etc and just generally help out when i am offline

anyway i can do this ?

The same way when you changed them to mod.

Go to admin panel > Users and groups > Group-> Group Administration > Administration ,click on modify ,then add the user id in that group of the member which u want to make as administrator...
