So if the page is a text-only page, the person was actually 'logged in' for only a fraction of a second.In other words, you can't do what you want, you can only guess at it. Try recording the time each person requests a page, then display the time instead of the date. Then other users can try to figure out who's still there by looking at the last time they requested a page.Sincerely, Ken Grome WebDNA Solutions http://www.smithmicro.com/webdnasolutions/...
