    Yes.  I logged out immediately loaded the cached page and just hit the Login
    button again and got right in.  On another machine, I logged in and logged
    out.  I let the browser site for 1 hour and repeated the previous
    experiment, I repeated with 2 and 3 hour intervals as well.  Each time, I
    was able to simply hit the Login button and log in.

                    This is not uncommon in web based email & conferencing
    packages, however,
                    most are authored to only allow this for a certain amount of
    time and to
                    disregard the attempt if the user logged out properly.  Out
    of curiosity,
                    did you test this with the two variables of time and a
    logout?
