I'm not sure if this really falls under technical issues, because this workaround isn't officially supported, but I would still like to see it fixed. Or, at least I would like to see if this was intentionally broken.
I am using a laptop that I won't use much, but I want to play SK on it. Since the laptop does not have Steam installed, I decided to use the online client. My account is converted to Steam, so I tried using the "Login into Facebook" workaround. The website script put the ID that my Steam account uses on this website; however I could not do anything with it. The client said to check the "login with Steam ID" box. The only box that I could see was the "Play as Guest" box. I tried putting my Steam password and just not putting anything in the password box, but it would say that my password is invalid. Am I doing it wrong, is this workaround broken, or was it intentionally removed?
