Sara, this has happened to me as well. I have discovered two reasons (at least I think I have). If I have deleted my cookies, my automatic sign in to Pet Talk has been deleted as well.

Also, if I just leave my computer on Pet Talk - eventually it will take me off and I have to sign in again.

I actually keep a small notebook on hand with all of my passwords and identifications.

Yeah, I know - all that stuff is hard to remember isn't it. I am doing good to remember my alarm code and my ATM pin.

Life is getting complicated with all of these names and numbers to remember.
