Glad I am not the only one who has this problem. I have to explain this to my dad about once a week. He tries to use his work email/password for everything and can't understand why it doesn't work. He seems to think that you can just log in to anything with that combination regardless of whether you signed up for the service or not. Guess it falls to the old saying of you can't teach an old dog new tricks.
