The MediaWiki open source project powers some of the largest collaboratively edited reference projects in the world, including Wikipedia, the fourth most visited website in the world.  This is our sixth year participating in Google Summer of Code.

If you want to massively enhance Wikipedia (example project idea), this project's for you!

You'll be able to view a portfolio of 2011 students' work here this fall, or you can visit the code links in this blog entry.
