Jessie,
No, that is not all you have to do.
You need to answer the ALL following questions please:

1 - Are you a YLD member? If so, we will update your email address for YLD. Please let me know.

2 - If not, and you are needing to change your email address for Yahoo groups, no one can do that for you, you need to do it yourself. Go to http://groups.yahoo.com and click on "My Account" (up at the top) to change your email for your groups.

3 - If it is for the newsletter, just go to http://www.radiantrecovery.com and sign up for the newsletter with your new email address.

Thanks
Kitty
