We're having 2 open hack days in Mexico City (Oct 2-3) everyone is welcome to join. There will also be a relay operator meetup Oct 2 @ 6:30pm.
You can learn more about Tor, hack on something with us, or just meet folks who are also interested in free and open source software, online privacy, and free expression.
Most sessions will be conducted in English, but some will be in Spanish. There will be speakers of multiple languages attending.
