If you've registered as a user (in order to comment) and never received a password please try the login link again and click "Lost your password?" and hopefully it will work. If it doesn't let me know. I don't think there's anybody registered who doesn't know my email address, or you could DM me on Twitter. Turns out that it was working for me but if your mail host was restrictive on the domain name of the mail sending machine the mail would get bounced. But now you'll get an email from Gmail so it should work fine.
