the server temporarily down right now for... mysterious reasons. we don't really know why right now - such is one of the problems of leasing a dedicated server. :/
but we hope to be back online soon!
and speaking of registration, there isn't a formal registration system in place, but we plan to implement a makeshift one pretty soon. as long as i have your attention, let me know what your in-game username is and i can pre-register you! :v
