Community Projects
From The Voxel Box Wiki
Community Projects are cities, or parts of cities, where anyone Member of The Voxel Box can build without prior approval or check-in. Most community projects have a "lead architect", who act as an overseer, and some guidelines to make sure the project remains organized and appealing.
Community projects are great ways to get started with short-term projects Becoming a Member, great for people who feel bored, and also a great way to learn a Texture Pack better!
Note: Leaving builds incomplete in a community project for an extended period of time may result in removal of the build.
