As a matter of course, I electronically sign as much of my online communications with GnuPG as possible. If you want to participate in this, the following information may help.

I can't read the attachment that you sent me in email! What do I do with it?

That attachment that you can't read is actually a "PGP signature". It confirms that I actually wrote the email you're reading. I rarely send email without a valid signature. Some mailers will automatically check the signature to verify the message's authenticity; others just show the signature as an attachment that you don't need to worry about. In general, just read the text of the main body of the message and you'll probably be okay.

Primary Key: 0x0C2EE21D

This key is used to sign most all of my emails; if something is not signed by me, it may be worth questioning why not.
