I'm sorry, I got there with one click... Here is the link:
http://www.cruisemates.com/articles/...tter/index.cfm
If you look above in the blue area below the ship you see the words "About Us" click on that, and in the drop down menu, click on "Newsletter".
That goes to a page that says "Subscribe to the CruiseMates Newsletter"
put in your first name (optional) and email address and hit the button that says "subscribe"
