well, oficial server tend to have the following, so if u wanna be oficial, do these (you still will only be oficial, if the dev want it.)
be online 24/7 hav ur own script have a static ip.
u then need a great group of admins, like have an admin online 80% of time.
u would need to keep this up for a few months, then, perhaps
besides, what makes ur server so special?
