how to communicate with the owners of the project?

1. A concise explanation of the problem you're experiencing.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you're using, your operating system and browser.

You can send an email to hello@cesium.com, open a GitHub issue (https://github.com/AnalyticalGraphicsInc/cesium), tweet at us (https://twitter.com/cesiumjs) or post on this forum!
