    Is it ever really necessary to log out from websites that require logging
    in, or can one just close the browser.

    I guess it probably is necessary for banking websites and suchlike for
    security reasons, but what about others ?

    You are correct on both counts. But understand that when you "log into" a
    site you aren't actualy connected to them like a telephonecall, you have
    just received a cookie from the site (which will eventually expire)
    identifying you so that you can do business there. Once the cookie
    expires, you are "logged out" without having to do anything else; closing
    your browser will log you out as well because the remote site won't
    see your cookie. Yes, for security reasons it is best to log out of
    critical sites such as banking, etc., but even then only someone sniffing
    your connection could then intercept the cookie and use it to impersonate
    you--highly unlikely. (I say "highly unlikely" with my fingers crossed;
    things are advancing altogether too fast these days....)

    They time-out after a while. If ou log out on some sites you get a
    redirection to advertising sites. Hotmail does it so you need to find the
    offending site details and add them to your HOSTS list. Then only a blank
    page or error shows up.

    If you're on a public computer like at a Library or coffee shop, then
    definitely Log out, otherwise as Gary said, its highly unlikely that
    anything could happen.

    It's best to always log out. But, it is not necessary.
