Ok, El-rock inspired me, so I went ahead and got us a mini minecraft server. It'll be always on, so jump in and build an action-teamy world with us all. It's a 4 player at a time max for now because I doubt more than 4 of us would ever be on at once, but I can change that in the future. That game is hella addictive and fun, do it!
For our Survival Multiplayer server the IP is:
(25x2) . (24-2).(10+7). (103+2) :25598
That's a lot of mathy skullduggery - I'm looking to see if there is a password pluggin, in which case I'd make it be what batman punched the joker into.
