I have a great idea to not have users enter qplay cookies! It may not work but I'm pretty certain it will.
Edit: I tried my best, but of course it didn't work. The problem was concerning security. I tried to use iframe to render the content of era and take the qplay cookie from there, but it was a security issue. I thought this over and now know why it's blocked: imaging if there was a non-visible iframe code on the page and it took your bank account cookie. Free money for the hacker... So it won't work tl;dr
