Hi! I co-founded Elgg in 2004, and Curverider two years later. I was in charge of development for its first five years, until April 2009. Although I have moved onto other projects, I still maintain an active interest in the Elgg universe. (Right now I'm working on OutMap and providing freelance web strategy advice and development services.)
Feel free to send me a message here or via email, or you can find me at my blog or on Twitter. Please note, though, that I am unable to answer specific queries regarding Elgg. That's what this community is for!
