CHANGING Your EMAIL ADDRESS for Yahoo groups

To change your email address for your groups:
First log in with your yahoo ID and password at
http://groups.yahoo.com/myprefs 
You will be taken to the page where you can add and change
your email address. 
After completing the steps, yahoo will send you a 'verification email'
to the new address you've selected or added. 
Then go to http://groups.yahoo.com/mygroups and click on edit my groups.
Where it says email address, change those all to your new address
Now you can go  and follow the steps again to delete the old email

If you have never gotten a yahoo ID, then create one and just subscribe to the mk-dfw list
