I am wanting to add a group listing into my email address book?

I received an email from school and want to add everyone on the list to my address book is there a shortcut to do this?

The best way I can figure to do this is to reply to the email using "reply to all," then say something like hi, this is so-and-so, or whatever. Then after you send the email, you should have the opportunity to add all the email addresses to your address book. After you add them, you can create a list and add all those addresses to the list.
