You can send email to (mailto link). I typically check my email several times a day; if I'm gone for more than a day or two, I ordinarily leave an autoresponse message with details.

If you use some form of OpenPGP, encrypted mail is accepted and encouraged; my public key is here.


You can call me through Google Voice. If I’m busy when you call, please leave a message and I will answer it at the earliest possible opportunity.

Instead of publishing my personal phone number on the web, I provide this callback tool, which will call you at the number you provide and then connect you to my phone.
