I just need a firm confirmation here, because I'm too afraid to lose the access to my multisite...
In topics around security, I did read that it's wiser to not have "admin" ID as administrators (or superadministrators) of sites.
So... I just created a new superadmin and also I gave it the administrator role in main site and in all subsites. So now I guess that user is totally equal to the original superadmin, right ? (except that it has a different email address otherwise I coudln't create that new user)
Now I would like to DELETE my original superadmin (who has the id "admin"), then give my new superadmin the email address that was originally attributed to my original superadmin.
Is it OK if I do that ? No risk ?
