Question about Yahoo! upgrade?

If you are using the clic mail, you may get prompted for awhile to switch to the new mail. You don't have to. I just click the x in the box and it goes away. It stopped popping up for me. You don't have to switch if you are using the clic mail, but if you have been using the previous new mail, that is the one that was converted to the newest New mail and you will get switched soon.
