Ubuntu Forums: ubuntuforums.org
This is a project I started back in October 2004 to fill a niche in the Ubuntu Linux market. After only a few months it became the official Ubuntu English forums and currently has over 140,000 members. In June 2007 I transferred over all ownership and rights of the forum to Canonical. However, I am still heavily involved as technical maintainer and chairman on the forums council.
Moxiedns:
Moxiedns is a opensource dns hosting platform built with php/mysql. It provides a fast and efficient front end to manage domains and URL forwards within Powerdns. I haven’t released this project to the general public yet, but stay tuned in 2009.
