Additional Admins, how to remove them?

[Luca]

...
I've succesfully added an admin (fictive) in a subserver...
How can I remove him from the system?
The message given upon delete command is: "You cannot perform this action on that user!"
Thanks!

Elxis does not allows that for security reasons.
You can only delete him via PHPmyadmin (table elx_users)

Tip: don't create multiple admin accounts. A manager or a custom group with access level between 70 and 99 (admin has 100) can perform most administration tasks and the admin will always be able to block or delete them at any time.
