Want to improve the coolest project on the planet? Too hard to build all of GNOME from source, just to use the latest development code?
Once you download it, you will easily be able to update it every day with PackageKit or Conary, so no need to download new versions. There will be new downloads available regularly, probably daily, so when you download it, it will be ready to go immediately, without waiting for additional updates. The best of both worlds!
Remember, there are many ways to get involved with GNOME, not just coding. We need documenters, translators, testers, and developers. For ideas, visit the GNOME Love page.
