Martha,
As for your official email address for YLD, I will forward your request to Vicki and she'll take care of that. She will need both your old email address and the new one, though.

For the newsletter, the best thing to do is go to http://www.radiantrecovery.com, and sign up for the newsletter over on the left of the page, using your new email address.

For the Yahoo email groups, you will need to change it at Yahoo!Groups.

Go to http://groups.yahoo.com and click on My Account (it may ask for your Yahoo ID and password so you will need to have those handy).

You can then click the Edit to the right of "Member Information" to remove your old email address and put in your new one (remember, you are putting these in the "Alternate Email" slot.)

Then you will need to go to each of your groups, go into the Edit Membership link, and pick the new email address as the one to use.

Hope that helps.

Thanks
Kitty
