Recently I made a silly mistake (fortunately it doesn't affect security): I have prolonged expiration date of my primary key, but not subkey. So sender(s) weren't be able to encrypt e-mail for me although I was able to sign my messages.
Now I have published updated key (0x500B8987)
at livejournal and on two key servers: pgp.net group (
one of them) and
PGP Global Directory.
