Green dots represent visitors that are or have been online in the past 5 minutes.
Red ones are a log of past visitors, updated every 24 hours at noon, France time.
Keep in mind that visits are not logged regionally but rather on a per country basis,
hence the single dot appearing in the United States for all the US users.

You can sign the guestbook to say hi or comment on
the accuracy of your location on the map (or the lack of it).
