At the bottom, under the question input, there used to be a magic box where you typed basically anything into it and it would log you in.
However that's now gone, and the new one is not better at all. It's just a Log In button. Which if you click, loses your question you've just spent ages typing.
It is extremely simple what needs to go there. A miniature version of the login page, with all the same buttons.
Or at least the previous text box, with a short explanation saying that you can just type your email address or URL (like gmail.com).
Please fix this, you have no idea how frustrating it is to lose the question you've just typed. And it's more frustrating when a feature is changed to something worse.
