Kyle Hasselbacher contact info

Web

My web page is http://www.toehold.com/~kyle/ and contains various flavors of information about me.

Email: kyle@toehold.com. You don't have to unmangle my address, but you may have to answer a challenge to email me. It's easy; just hit reply. More tips below.
Postal mail: My current address is generally on my domain record.
Phone number: Also on my domain record.
Other: Ask me for IM info or any other wacky channel you want to use but don't see here.

If I've never heard from you before, and you want to avoid getting a challenge when you email me, here are some tips.

Use this address: kyle-exp-1210743901.b1e1a5@toehold.com. It expires soon, but it should be good for at least 30 minutes from when you got this page. Refresh for a new one.
Send a PGP mail. Emails signed by a PGP key found on the the key server I use or encrypted for my key get in free.
Include Hashcash in your email.
I prefer encrypted email. My mail reader can read PGP/MIME. (See also Why do you need PGP?)
I dislike HTML mail.
If you do get a challenge, the envelope sender will be <> and Reply-To: will be set to something like "kyle-cnf-1234567890.1234.abcdef@..." The subject will be "Please confirm your message".
