Try creating groups, then send to the title you gave to each one. Try it this way in Yahoo Classic: 1. Click the "Contacts" tab at the top of your yahoo mail page to open your address book. 2. Put a check mark next to each name you want in a category/group. 3. Click the "Add to Category" tab above the address book. 4. In the new drop down menu, click on "New Category." 5. Type the title you want to give your category into the box that opens in the upper left, then click OK. Do the above for each category/group you wish to set up. The name of your category appears in the left navigation bar of your address book under Categories" but this one is for editing only. When you wish to send email to a category, after you click on Compose or Forward to open the message window, click "TO" to open your address book which is set up for emailing. At the the top of this mailing list, click on the little blue "categories" link across from 'Contacts" to open your list of Categories. Check the box next to the category you wish to send to, go to the top and click on "Insert Checked Contacts."
