I would like to know why I can't log off ? I log off for the day but it keeps me logged in, what is up with that?

Could be that your cookies have been established, and when you left the site...as I do...it's automatic.
When you return to the site, you're automatically 'logged in'.
However, I'm not the computer guru...

more that likely, I must get them out.

good cookies and bad cookies

good cookie's=allow you to remain logged in without having to actually login over an over

bad cookies= all the porn sites keep flashing up at the most inopportune moments

well waddya know? I'm a Gunny again!! Rounds are on me!!

I found out that if you go into a site, and 'log in' there's a box that asks you 'remember me on next log-on' or, 'log-on automatically' will retain your settings.On my personal machine, I will choose that but on a remote system I won't. Purging your history and cookies will over-ride those settings and you will have to 'log-in' the next time you re-visit the site.
Hope this is helpful.
