Is it right, that the only way to change the username of admin, is to do it manually in the database with phpmyadmin? If I do it that way, can this cause any troubles? I guess not, unless the username "admin" is hardcoded somewhere (which hopefully is not the case). I like to avoid obvious loginnames (like root, admin, administrator).
Oh boy, what a stupid question, I should have done more looking instead of instantly posting. All the admin details can be changed under System >> Edit user (Form to edit systemusers). Didn't look there at first, but at Tools >> Password and Language, where you only can change these two, which is quite confusing and redundant.
