The compass always points to Terrapin.
Has everything you need to know, (I think).
Except for the User ID info. That's the part that I don't know how to send into BGG. I'd like to do it so that I don't need to click on a link; if I didn't mind clicking on the link, my browser's cookie would automatically get picked up and there would be no issue. To do it programatically, however, requires me to either replicate the cookie (and I have no idea what the cookie is named, or what info is sent) or send it in on the command line, which I'm willing to do once I know what to send.
Thanks for trying, though!
