For meeting up at Defcon 26 this year, the SX Crew has decided to utilize the Mojave Phone Booth for anonymity. Preferred method is Signal (signal.org) but SMS also works. In order to join, send subscribe <nickname>
to +17607339969 via Signal (signal.org) or SMS. Blake is generally on there, so you can /msg blake <message>
to get a private message to him. In the past I have said to email me, but this often doesn't work last minute.
Feel free to reply to this thread if you are planning to be at Defcon 26 and feel the need to announce
