I see tons of my friends drop by my server and its always tough to choose which ones have admin. Although I managed to narrow it down to 12 admins. Wait....oh not to post admins.
Anyway, I would see an admin that would build something important that I can't build (I'm not that lazy but sometimes it matters), a good friend on other servers, gave me admin on their server (most of mine don't host servers and I also see eye for eye as well), and doesn't abuse admin (teleing, cheating, and/or banning).
Don't get me wrong on my expectations, my admins are very good ones.
