Can I change my license's admin address?

I would like to switch my premium administration account to a different address, but I see no option to do so.

Sure you can, simply follow these steps:

1. Access your private area with your current admin account.
2. Click on Settings.
3. Select Assign administrator role.
4. Search for the user account you want to transfer the admin role to.
5. Type in you current administrator password and press Transfer rol to finish.
