Having trouble logging in?
Make sure you're using the correct address. You should have received a confirmation email when you signed up. Look for it and make sure it's the same address you used to log in.
It could be that you changed email addresses at some point and the old address now bounces messages back to me. If this happens too often, the old address will be unsubscribed automatically. The easy thing to do is sign up again with your new address.
If you're still having problems, let me know and I'll fix it!
