You signed up for the %(party)sPGP Keysigning Party with the following key:

However, I have not been able to find your key. I have tried the following
keyservers:
%(keyservers)s

Please upload your key to one of the aforementioned keyservers. You can do
this simply with:

  gpg --keyserver %(keyserver)s --send-key KEYID

Where 'KEYID' is the keyid of your PGP key. For more information see this site:
  http://www.phildev.net/pgp/

Your key will be searched for again in 24-48 hours and if your key is not there,
you will receive another email.

You do not need to contact me if you upload your key. If you have questions you
may email %(from)s.
