GPG Keys and Signing Messages To This List

[Graham]

I don't know if anyone is experiencing the same problems as me when 
trying to follow posts that have been signed by GnuPG.

Very often (in Kmail, Sylpheed-Claws, and Thunderbird/Enigmail) 
posts"hang" while the MUA checks with the keyserver, and only finally 
does the message come back that no public key could be found on the 
keyservers.

My default keyserver is subkeys.pgp.net but I have also tried 
earth.net.uk.pgp.net and sks.dnsalias.net with the same effect.  Some 
keyservers (and this applies to subkeys.pgp.net) are aliases for a 
whole group of keyservers which get updated when a key is exported to 
them; other get synchronized with each other several times a day.  So 
the only real reason that a key is not on the keyservers is that it 
hasn't been exported to them.

Could all using GnuPG and using public keys to sign their mails to this 
list, please ensure that their public keys are exported to OpenPGP 
keyservers?  Thank you.
