Every time I look at the AF site, there's the "Who's online" thing in the left margin. Right now it says "There are currently 3 users and 745 guests online." It's 8:45 on a Saturday morning, so while the 3 users may be accurate, where in the world does the 745 guests figure come from? I realize that AF reaches more than just those of us fortunate enough to live in the heartland of the United States (CST), but still... 745 guests?
I guess the crux of my question is, how does the site determine how many users and guests are onliine?
