beunited.org (and people united there) have something for developers:

"For about a week the development site for beunited.org projects has been available to the general public thanks to the work of our Director of Developer Relations, Paul Ashford.

The site lists the projects currently available at beunited.org and provides cvs access via browser access to open source code.

The site will eventually mature into a full fledged developer portal with individual pages for each project. More work is being done on this site daily, so keep an eye out for new features. All suggestions are welcome."

Good! Now bugs will be squashed faster and great applications will be even greater!

Are You a developer? What are You waiting for? Go there and play! :)

I already use the newer ArtPaint with the fixes by Segei "fyysik" Dolgov (try searching for ArtPaint on BeShare).

Update: You can get fixed ArtPaint here THX to fyysik :)
