An event at which GPG users get together and authenticate each others identity to build the WebOfTrust. Usually a minor (and very geeky) part of LUG meetings, conferences (particularly Debian and KDE conferences, because these groups rely on GPG authentication as part of their organisational infrastructure) or other gatherings of the cryptographical aware.
Big Lumber (
