Hi Paris--   Yahoo changed their address book so it's only a tiny little box organized by first names; the previous format was organized on pages and by last name.  I can't stand it!  I have to search all up & down the one list now for all my relatives with the same last name?! --Gwen

OK, Gwen.  I'm not a Yahoo mail user, so I went and set up an account to see what you're talking about. I see a Contacts folder.  I see that the Contacts can only be sorted by First Name or by Email Address.  That seems crazy.  Lots of people want to use Last Name to sort.  So I see a link at the top to use "Classic Mail"--I tried that.  Very different look, but again, the Contacts can only be sorted by First Name.  Interesting, though, when I switched from the new Beta to Yahoo! Mail Classic, I got the chance to give them feedback, so I told them about not being able to sort.  Also, when you use Classic, the Help section has a "Send Feedback" form that allows you to send in your request.  I suggest you use that. 

On their user forum, I found other users as frustrated as you are: http://tinyurl.com/muh9dw

So for now, complain.  Hopefully, if enough do, they will return the ability to sort by "Last Name. "
