ISC is facilitating a PGP Key Signing Party at the NANOG 31 meeting in San Francisco.
After noon on Monday, 24 May, the keyring for this event will be linked from this page for your downloading pleasure. Keys for the keyring will be harvested from e-mail, as per the instructions, and also from the keyring hosted at Biglumber (try a quick search for "NANOG" to find the keyring there). Feel free to supply your keys in whichever way suits you best.
Biglumber is cool, and you should check it out if you haven't already.
