I loved this article on Lifehacker on how to add a “Send this story to Gmail” send to menu in Google reader, except I use Google for Domains and it doesn’t work with this.  So here is how I did it for my domain.

Replace “cpuangel.com” with your domain

Name Full Gmail

URL https://mail.google.com/a/cpuangel.com/?fs=1&tf=1&view=cm&su=${title}&body=${url}%0A%0AShort link%3A${short-url}

Icon URL http://mail.google.com/favicon.ico

If that doesn’t help, see the example below.

Enjoy!
