If you want to get in touch with me, your best bet is by email (cgf@syntilect.com). In fact, I typically forget stuff unless it sits in my inbox to remind me. I also use:

• Mobile Phone - +64-27-666-8500 and +44-797-2111-006
• Snail Mail - Exeter College, Oxford, OX1-3DP, England
• Skype - christo.fogelberg

If you want to send me encrypted mail, or verify something I have signed, my public key is available here
