Down on the bottom, to the right of where it says how many are here....there is an underlined "who's online". When I click on it I get taken to a map of the world with little bubbles to show where the registered members are located (more or less close to where they live). If you tap on the screen...oh, maybe that's because I'm using this iPad.....well, anyway, I tap on the screen to make it zoom in and it shows closer where the online lurkers are. Maybe we ARE interesting to some people - LOL
Oh, there is also a thingy where you can move the line and it zooms in to make the map larger....over on the left side of the map.
