JandyAF MUST be logged in (even if it's happened automatically because she's got them the login details stored by her browser), otherwise she couldn't have posted.
However it's possible to simply view the site by closing the login/register box which appears, instead of filling in the details.
Hi ateglo65 - it sounds like you might be regularly clearing your browser cache/cookies. This will lose the "remember me" part of logging in to AB. Do you have your browser set up to do this when you close it?
