It would be easier if we can hide the super admins from the memberlist and hidden from public (If there is a way please let us know!)Do NOT use your Super Administrator account to address anyone, make any announcements, or do anything that could associate it as you or anything officially associated with your site. The point is so that no one knows what your Super Administrator account is. Make a hello thread, post a few simple replies, so it's not just an account with 0 post, then leave it alone.
It's possible with additional coding. But with both file and template edits it should really be an addon. You should post a request:As i requested in my thread too, is there a way to have a button to sort the list in more than one way, eg button: "Sort by Posts" If I hit the button, posts are sorted by number of posts.
