Toast, FYI I couldn't setup my account until I filled out the (optional) email field. Thought you might like to know.
I didn't fill that field out and when I submitted it said 'all good, login now' or whatever. Couldn't login.
After filling out the email fields, I was able to login and now I'm Hashing away Happily on your server.
Arachnid, not sure what the issue was exactly... I just tested myself by registering another account and I didn't have to fill in the e-mail address. I verified it did indeed create the account as I was then able to log into this test account without issue. Maybe just a one time fluke??? Please let me know if this happens again!
