I keep meaning to post about this and then I forget to. Then I remembered!
During the SF Bay Area store championship series, I noticed that there was a lot of work required to enter lists into List Juggler. While there currently exist ways to enter them (via the YASB URL or Voidstate's squad ID), what usually ended up happening was one person would end up with all the list printouts, and would have to enter them manually anyway.
So a few weeks ago, I added a QR code to YASB printouts. (There's an option in the print dialog to turn off the QR code if you want.) Now, the TO (or whoever's doing the list juggling) can whip out their phone and scan that QR code which gives you a mobile-friendly URL that, when visited, lets you select a tournament that's been created in List Juggler. (You can search for a tournament by name or venue.) Once a tournament is selected, you can choose from players already entered in that tournament, or you can enter a new player's name.
Enter the email address of the person who created the tournament in List Juggler, submit it and presto! That list is added to List Juggler.
The Juggler entry page will remember the email address and the last tournament you searched for, so you don't have to pick it every time if you're entering several lists for the same tournament.
Hopefully this will be helpful for future tournaments.
