WLB,
I decided to actually log into FF and list the steps to include your chart. I hope they help.

In FF go to Sharing and then to Home Page Setup, follow the prompts there and then it should give you a link - for example mine is 235b3f Ovulation Charts and then you can copy and paste that into your signature or into a message.

If you want it like mine and have the link called "My FF Chart" then in your signature you need to put it into a coding without the spaces it looks like this [ URL = "http://www.fertilityfriend.com/home/235b3f" ] My FF Chart [/URL]

I hope that helps you... I am very intrigued to see this chart after all this he he he

Mummymoni, I have only used FF... not sure what other programs are out there.
