We have been a community since May of 2011 and boast a featureset that was written right from our development team.
A few of our features include:
Lot system which allows you to get an area that only you and people you allow.
Protect/Restrict various blocks (chests, trapdoors, doors, etc.)
Multiple worlds (Survival, Aether, Nether, Creative/Pixel art world and a resource world)
And more!
Ranks:
VIP – Access to 3 100×100 lots.
Super VIP – Access to up to 5 150×150 lots, TinyWE usage, lights anywhere (places glowstone at feet)
Goldy – Infinite lots up to 300×300, backpack, larger TinyWE selection, prefix editing!
New features are added more and more with each update. Staff can be found on forums or in-game.
