Here are the main open source software projects I have been involved in.
b2evolution
b2evolution is a blog/content & comunity management system. There is also an unofficial blog for it ;)
Stut-One
Stut-One is server software for the French Minitel. This actually pre-dates the Internet as we know it. It was a time where being online meant black and white text displays and paying quite high fees by the minute!
