I've been a Yahoo user for over 30 years. In that time I used Yahoo Groups extensively, then Yahoo took it away. I've used email that whole time. I also used My Yahoo at least 20 years and now you are taking that away. This is an extremely BAD idea. I've gone out to look at what you will be replacing My Yahoo with and to be honest, it is terrible. The main reason is you can not personalize it like you can your My Yahoo. If you take My Yahoo away, that leaves me only the Yahoo email. I will definitely start to look for another main email site and leave Yahoo all together. This is just my opinion.
