I don't care if you're super admin, although I guess it wouldn't hurt to remove you - I can just give you full admin access from your profile. But what does matter is the undeletableusers variable. I don't know if being Super Admin automatically makes you undeleteable. I know Amit is Super Admin, and I was able to edit his profile, but he may not have been added until after I edited it.

More importantly, FTP needs to change. Garfield said he didn't know it and to ask you. As far as I'm aware, you're the only one who knows. If you can access cPanel, you should be able to change FTP from there.
