Once you've sent off your first dues to the Treasurer@puzzlers.org, you're going to wonder how this all starts.
Fairly quickly, you'll receive your welcome package with the latest three issues of The Enigma. Each issue has a two month solving window, so you can verify your solutions to the puzzles in the oldest issue with the solutions appearing in the most recent issue. Many members send in their solutions, either from solo or team solving, and track their solving statistics. Instructions on how to send in your solutions are in every issue.
Then you should also set up your account on the website. Visit Website Access and Passwords for instructions on how to do that. You'll find more information there about how to subscribe to mailing lists and things, too.
