Contact information

My email address is mark (at) celos.net.

Obviously you'll need to put an at symbol in the appropriate place. If you want to contact me by post, or by telephone, please send me an email and ask for the relevant contact details. If you want to write to both Sarah and I, you can use sarah+mark (at) celos.net and copies will end up in both of our mail accounts.

You can sometimes find me on undernet in #userfriendly, or via AIM; my nick (and screen name) is Ytheleus in most cases.

Public Key

My public key used to be available from most keyservers, but the most reliable and up-to-date copy is on this page. If want to sign it, please let me know (and send me a copy). If you do search for it, there's a lot of Mark Whites out there, so you'd be better off searching on email address, or on the KeyID, 20104CA8. This key has at least one revoked UID, but although that's included in the keyserver copies, they often don't tell you about it in their listings; please don't assume that all the listed email addresses are valid.

The easiest way of getting it is here:

GnuPG is good and interoperates fine with PGP 5 onwards. If you reall need to use encryption but can't manage to upgrade from PGP 2.0 or thereabouts, ask and I'll do my best.
