Hello Jason,
I just signed up with GDI as well... By the way, thank-you for your service to our country!
I believe I did see several links that you can send someone, in particuliat a TAF (tell a friend) format page. If you cannot find a quick fix answer, you should be able to simply start playing the presentation, copy the address from the browser and paste it to a letter you are sending someone.
Another way I'm going to be promoting GDI is thru VIDEO EMAIL which is far way too easy to do.
Brian
