--- Comment #9 from Austin English austinenglish@gmail.com --- It worked for me using wine-10.0-rc6 (Note: I closed the original tab that opened in firefox by mistake, and then used 'Copy URL' in the application and pasted that manually, which may have made the difference).
Retrying a second time and it seems like the site remembers my computer (even in incognito mode, so presumably it's by IP).
