My main email address is james@tartarus.org. I have a bunch of others for more specific tasks, and it should be pretty obvious if you need to use one of those. I won't list them here because they're irrelevant for personal communication.
If you don't want governments the world over to know what you're saying, you could try verifying my PGP key somehow and encrypting what you send. Note, however, that this will take ages because I have to transfer it onto a more trusted machine first. You probably want to use the email address listed in that key, ie: pgp@james.tartarus.org.
If you really know what you're doing, then you may be interested in my insecure PGP key. Beware: this key has insecure all over it. This is because the private key is stored on a highly connected network server. While I maintain the server, I cannot guarantee the security of the key. I do not trust the key for critical communication, and neither should you. You cannot guarantee that data encrypted with this key is readable only by me, or that data signed by this key was written by me. In the former case, this is no less secure than unencrypted email (although the encryption may provoke shadowy monitoring types to pay closer attention). I'm not going to sign anything with this key (especially other keys!), so be very suspicious of any such signatures. (If I change my mind on this I will amend this statement and provide a signature created by my real key. I intend to do that anyway for this statement when I get the chance.)
It is best to treat the insecure key as encrypt-only, and not to treat it as secure even then. (However I encourage anyone so inclined who isn't concerned about privacy to start off with to encrypt all traffic to me using this key, because encryption isn't evil.) You may want to use the email address associated with this key: insecure@james.tartarus.org.
