When trying to sign up, I miss typed my password and they did not match and got the "Passwords do not match" error. I typed them again, making sure they matched, and got the same message. And again. Opening Chrome, I tired to sign up, only to find my username was taken. I did not necessarily believe this; so, I tried the forgotten password link and entered my email address. 33Mail sent me the link to reset my password, which I did, and logged into the system. I had a notification that I had not confirmed my email address -- I had never gotten the message -- so, I had it resent. The confirmation message arrived and I confirmed it. Anyway, although I did not get past the "Passwords do not match" error, it did sign me up; but, did not send an email for me to confirm it.
