Tomorrow (Thursday 15th November), there will be a PGP key signing and CAcert assurance party in Prague. It will be held in SUSE offices and it will start at 17:00.
If you are interesting in having your PGP key signed, bring papers with your key fingerprint (you can use for example these slips) and some government issued ID. For CAcert assurance it is recommended to bring printed out assurance papers (you can get them from CAcert website) and of course IDs as well.
You can find more information on Facebook or Google+ event pages.
Did my annouce or two French signing parties wake you up? ;-)
Thanks for the URL of the paper slips generator, that should be useful!
