2Speced is down. For good. Just wanted to let you know.
OT: Umm.. You could try RuneMyth, SilabGarza, Near Reality, Yanillescape, LostPkz (It's up again after a long time. They had like 400+ people on back in '09. Though they hardly reach a playercount above 20 nowaday), BattleScape, WebsterScape, HackScape, and last, but certainly not least: Deltascape. It's one of the best servers ever created! I'd give it a try if you haven't already.
They're all great servers, IMO. But if you're looking to pk, and pking only, than I suggest Near Reality. You'll love it! Though I suggest checking out these other servers as well!
