I think it might be a good idea for at least one admin to be on the server if there isn't one because when there aren't any admin, a lot of people button spam, or mess with people, and break rules and crap. Just a suggestion
Most of our admins work on a North American time zone, usually we're all asleep for a good 10 hours or so, and even then some of them might not get on till around night time. At the moment 24/7 admins will be impossible.
I'll get some things set up soon to help out the server though, just give me a week or so.
