Looks like we've solved our intermittent mail delivery problem. If you were expecting a registration or key and didn't receive it here's what to do:

If you never received your web site registration:

• Go to http://www.opencalais.com/user/password
• Enter your email address or user name
• Click the button

If you never received your API key:

• Go to http://www.opencalais.com
• Log in
• Click on "Get or retrieve an API key" 

Regards,
