When you log in there is a small box to the side that says "remember me" If you don't click that when you close your window to leave fishLore it will log you out and you will have to log back in and re-enter your password when you come back.
I'm not sure i would like being automatically logged out though. When I'm home I stay logged in and go back and forth doing things around the house as well as at fishLore.
I'm sure there will be others in to give their thoughts on this also.
Have a great day guys !
