Ok, so there's not much to see yet, but at least I now have something.
My PGP key downloadable from here, and is
also on
the public keyservers; using something like
"gpg --recv-keys 4377B37D
" should retrieve it.
Its fingerprint is "4D2C 6563 C4E6 64E8 8490 4B36 E1F7 38DC 4377
B37D
".
This key should be used in preference to any older ones that you may come across. I've signed the new one with all the previous keys I can find – or at least those to which I remember the passphrase – in an attempt to add authenticity, but please don't trust it unless you're 100% certain it's really me.
