What do you suppose are some qualities of a good server host? If Tom and Tim are both hosting a deathmatch server, what is better about Tom than Tim and vice-versa?
I think some important qualities are flexibility (being able to change things when you must), patience (so you can work with as many people as possible and put up with some degree of annoyance), and reliability (so whenever you're needed, you're there for someone, some people, or something).
