We've gotten quite a few questions about how to access the digital version of the guide on computer and mobile. Once you've received your 5-letter KEY (it can take 2-3 days sometimes...), you enter it into the member key field at http://lobbyguide.truscottrossman.com/.
If you entered the right code, it should forward you to http://lobbyguide.truscottrossman.com/memberlist. Save this link! It's the location of the Lobby Guide. As long as your browser accepts and keeps cookies, you'll never have to log in again.
To add the app to your iOS, Android or Windows device, check out this great tutorial.
