Broken here too.
Login page keeps asking for my email and PW, which I provide.
Then it tells me they don't match.
So I click "Forgot password?" (altho I haven't actually forgotten it).
Then it tells me they've sent me an email, which never arrives.
Wash, rinse and repeat. Wash, rinse and repeat.
This is adding new excitement to my morning. Hope it's fixed soon.
