According to my resume, I've been contributing to Haiku since 2002. I don't remember how I determined that start date, and GMail is only five years old so searching that does not provide me with an answer either. What I do know is that I feel a strong connection with this project. Which really makes it all that harder to part.
I remember I started by writing a naive proposal about internationalization back when this was still OpenBeOS. You should know that at the time I was sixteen years old, so I never really knew BeOS, and I just came from the translation team from KDE. I left that project in search of something bigger, more integrated, more ... I think we have all been there. BeOS seemed like a materialization of that dream. Only, Be Inc. already turned into ashes when I started my quest. A bunch of silly coders with a vision were determined to continue that dream. Little did they know that seven years later their code would boot on many machines - even though mine right now seems to be left out of the fun. My proposal on internationalization, however, never came to materialize.
