The symfony blog has announced a new initiative for developers using their framework to get involved in - creating a website for a cause. The first step? Identifying the causes:

This event will take on the basic structure of other 48 hour web application development competitions, such as Rails Rumble, but with a special twist unique to symfony. The applications we create during the course of the competition will be gifted to different socially-minded organizations around the world. Once the fun is over, our work will live on and hopefully do a lot of good.

Since the first step involves identifying the causes the sites will be created for, they've laid out a few guidelines to help you submit the cause of your choice.
