So, I've made Yahoo my home page..now, to check my mail, I still have to type in e-mail addy plus pword..WT?

Yahoo does this to protect your information. Make sure you are signed in and the most you will have to do is enter your pword. Again, this is for your security. Go to mail options next time you sign in your pword and make sure you have the option, remember username checked on the sign in page. Hope this helps.
