GlimmerCraft is a survival build server with multiple worlds and massive 61x61 plots that spawn infinitely, and can be claimed automatically. It has a PVP arena and a player-personal scoreboard that stores all your PVP stats. The spawn is filled with shops, if you don't want to venture into the unknown. Each world has their own set of blocks to be collected. To get a list of them to warp to, do /Warp.
We currently need staff, but if you join the server don't ask for it. After a few days of being online and showing yourself to be trustworthy, we will talk with you, and if it goes well, we'll promote you.
Best of luck and good building!
