Back in 1997 I was involved in starting Catalyst IT Ltd and I turned up there to work for the best part of 11 years. I've retired from Catalyst in 2008 so I can spend more of my time working on free software.
An e-mail addressed to andrew within the McMillan domain will reach me just fine, but with around 3000 spam / day being bounced I guess that's not too hard for people to work out. Or you can phone me on my mobile on +64 (27) 233 2426 - that's 027 2 DEBIAN for people in New Zealand. Hopefully that provides you a clue, perhaps, that I am a fan of Debian GNU/Linux, and I have been a Debian Developer since 2002 or so.
I've also been involved in a few other organisations including being a member of the national board of Parent's Centres New Zealand for a few years and the president of the Wellington branch of the New Zealand Association for Gifted Children.
