I designed the RaccoonOnMap to request the location of the users only when somebody has the web page open. Reason for this was to save data traffic and battery of the phone. The RaccoonOnMap page actually refreshes itself every 10th minute so if you leave the page open then ROM server will request the location of all users every 10 min.
If you want to make sure that you are "spotted" (e.g. to save the GPS coordinates of a new cell) you can request yourself your own location by calling the ROM server with your phone's own web browser:
In my N80 this was little tricky since the memory was low and opening web browser usually killed Raccoon. I managed to make it work by first starting the WAP browser and then the Raccoon (both using the same access point).
