Screenshots let people get a feel for your work, and is the most important part of a node. They should be the correct size, and have no heads up display elements. Refer to the User's Guide for information on how to fix this.
I've got big plans for the {m00c0w} clan (or {m00} for short). Thanks to my friend Snuggles, we have a server up and running (Look for "{m00} moocowclan.net" in the MSL). Coop-Edit is always our top pick, though all players and game modes are welcome for now.
The feature-rich site will have clan news, current project information, a blog, server status information, a forum, a screenshot gallery, and much more. You don't have to be a member of {m00} to visit, but accepted {m00} members will get special bonuses, such as the ability to schedule coop-edit sessions with friends and collaborate on maps and projects.
Right now, I'm working diligently to get the site started as soon as possible but it's a lot of work. If you'd like to offer any coding/testing/designing help, let me know. ANY questions, suggestions, help, ideas, or criticisms are welcome.

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.
