If you talking about reading and posting message in Yahoo groups? If so, there is not necessarily a link back.

However the easiest thing to do is go to
http://www radiantrecovery.com

When you get there, add it to your Favorites in your browser. If you are using Microsoft IE, go to the Favorites link at the top of the window and then click "Add To Favorites".

Then whenever you want to go back, just click on favorites and the link should be on your list of favorites. That way, you can get to the Radiant Recovery page easily from anywhere.

Hope that helps,
Kitty
