I use Yahoo the most. It has that new feature that will keep you logged in for two weeks even if you restart your computer. I also use it as my homepage and can get to my mail by hitting the "home" icon on IE. I sometimes use MSN mail. I really liked the AOL mail when I first used it. It is very unique how the window would pop up and not look like a web page. p.s. I called it a mail program because I didn't know what else to call it.
