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 100x100 lots.
Super VIP - Access to up to 5 150x150 lots, TinyWE usage, lights anywhere (places glowstone at feet)
Goldy - Infinite lots up to 300x300, 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.
