For about a month now, Yahoo! won't acknowledge that I am logged into my account and allow me to rate or comment on most of the articles. I can read other peoples comments, but I can't participate in the dialogue. Whenever I try, Yahoo! wants me to enter my password. Although my screen name is always present, it won't hold the password. This has become VERY annoying!
I'm very sorry to hear that you are having trouble staying logged in. That does sound incredibly frustrating!
