Terrible Yahoo interface and performance!
The multiple instances I've heard from other people and personal experience I have had myself indicate that you are on the bottom of the quality spectrum with respect to email and social communication networks. In this case I get an error when I try to send emails to the people in my fantasy basketball group that my reply to address is not verified. In repeated attempts to go into the settings to find out how to change this reply to address I am frustrated again as some other friends and family members have indicated to me there frustrations with your interface over the past recent years! You want people to pay you money to get you to help them navigate through your poorly designed and ineffectual system. You are garbage!
