The site maintains a strict policy of only having content that is of value to the public in some way. Content should be thoroughly worked on before submission, and a node will be unpublished if something remains seriously wrong with it for a long period of time.
If this is a map, it could mean a problem with the lighting, texturing, geometry, or layout; try the Cube Wiki for tips on using the engine. Should it be some other form of content, then it may need to be elaborated upon to be worth something.
The layout of a map is among the most important parts of a winning design, try making sure exotic geometry is removed or clipped and the level is open and free of dead-ends or unexplained phenomena.

My first (decent) map. It is designed to have enough room for about 2 - 6 players in a fight to the death. I recommend enabling "glare".

Constructive critiscism is welcome, tell me what you think :D
