We now have a voting system: https://www.massivecraft.com/vote
You can vote 3 times a day and each time you get nice rewards.

Right now we have 500 player slots and in a few months we will have 1000. The player slots are no longer a bottleneck for the growth of our community. The time has come to invite more players! Your vote matters! Through your support other players find their way to MassiveCraft and our community will grow.
