also have this problem. my roomate and I share a computer. sometimes when i log into my account HER email shows up. or if I do get my email, when i go to favorites, i see her favorites and not mine. it's like we each get part of our own and part of each others information. Makes it very hard to keep it all straight, not to mention maintain our own privacy
