We have been running our server for around a year, and constantly upgraded it with most recent mods. Currently It is mature enough to invite people to visit and play and soon to help testing with new AtlantisMP mod (forcefields, turrets, misiles, weapons, flying (yes you can fly your city as spaceship :P) cities, exploration vehicles etc)
for now server is WHITELISTED - write me PM to enable access for you.
SERVER ADDRESS : gminecraft1.ttq.pl - the same as website address
map is available through : map.gminecraft1.ttq.pl [[dynmap]]
Additional tweak/support small mods :
tree capitator 2.0.3
