It would be an improvement if Yahoo would not make changes like this. The old adage "If it is not broke, don't fix it" should be on your agenda at all times. Changing formats and giving us no choice in the matter constantly is leading you to lose even your most loyal users. I didn't like it when you changed the mail format but I still stuck with you but I don't think that I can stand too much more of change especially when it is NOT for the better.
