Over the years I’ve organized or tried to organize pgp key signing parties every time I go somewhere. I the last year I’ve organized 3 that were successful (eg with more then 10 attendees).

1. Have a venue

I’ve tried a bunch of times to have people show up at the hotel I was staying in the morning - that doesn’t work. Having catering at the venues is even better, it will encourage people to come from far away (or long distance commute). Try to show the path in the venues with signs (paper with PGP key signing party and arrows help).

2. Date and time

Meeting in the evening after work works better ( after 18 or 18:30 works better).

Let people know how long it will take (count 1 hour/per 30 participants).

3. Make people sign up

That makes people think twice before saying they will attend. It’s also an easy way for you to know how much beer/cola/ etc.. you’ll need to provide if you cater food.

I’ve been using eventbrite to manage attendance at my last three meeting it let’s me :

  • know who is coming
  • Mass mail participants
  • have them have a calendar reminder

4 Reach out

For such a party you need people to attend so you need to reach out.

I always start by a search on to find who are the people using gpg registered on that site for the area I’m visiting (see below on what I send).

Then I look for local linux users groups / *BSD groupsĀ  and send an announcement to them with :

  • date
  • venue
  • link to eventbrite and why I use it
  • ask them to forward (they know the area better than you)
  • I also use lanyrd and twitter but I’m not convinced that it works.

for my last announcement it looked like this :

Subject: GnuPG / PGP key signing party September 26 2014
Content-Type: multipart/signed; micalg=pgp-sha256;

This is an OpenPGP/MIME signed message (RFC 4880 and 3156)
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

Hello my name is ludovic,

I'm a sysadmins at mozilla working remote from europe. I've been
involved with Thunderbird a lot (and still am). I'm organizing a pgp Key
signing party in the Mozilla san francisco office on September the 26th
2014 from 6PM to 8PM.

For security and assurances reasons I need to count how many people will
attend. I'v setup a eventbrite for that at
(please take one ticket if you think about attending - If you change you
mind cancel so more people can come).

I will use the eventbrite tool to send reminders and I will try to make
a list with keys and fingerprint before the event to make things more
manageable (but I don't promise).

for those using lanyrd you will be able to use

ps sent to, end - please feel free to post
where appropriate ( the more the meerier, the stronger the web of trust).=

ps2 I have contacted people listed on biglumber to have more gpg related
people show up.

5. Make it easy to attend

As noted above making a list of participants to hand out helps a lot (I’ve used and my own stuff to make a list). It make it easier for you, for attendees. Tell people what they need to bring (IDs, pen, printed fingerprints if you don’t provide a list).

6. Send reminders

Send people reminder and let them know how many people intend to show up. It boosts audience.

We just released the first beta of Thunderbird 30. There will be two betas for 30 and probably 2 or more for 31. We need to start uncovering bugs nows so that developers have time to fix things.

Now is the time to get the betas and use them as you do with the current releaseĀ  and file bugs. Makes these bugs block our tracking bug : 1008543.

For the next beta we will need more people to do formal testing - we will use moztrap and eventbrite to track this. The more participants to this (and other during the 31 beta period), the higher the quality. Follow this blog or subscribe to the Thunderbird-tester mailing list if you wish to make 31 a great release.

In a a few weeks it will be Fosdem week-end. Something I’ve been attending since 2004.

This year I’d like to tell people that care about email privacy that fosdem has the biggest pgp key signing party in Europe. If you use pgp, or gnupg you might want to join the party.

To do so you’ll need to register before the 30th of January and follow the detailed instructions at .

update: People are sending plenty of keys it’s going to be a great event.
