Please sign and — in particular — encrypt any mail sent to me using my OpenPGP signature and yours. I like to keep my correspondence private, and I like to verify my correspondents with their signatures. Since I probably don't have your signature, please give me the link to your launchpad.net user details page, which of course should contain your OpenPGP key on it. Similarly, you'll find my key on my user page, which you are currently viewing. :-P
