An interesting idea has be brought to the TikiWiki site by ang. He has started work on plotting locations of the TikiCommunity onto a XPlanet map. You can see the result here Community Worldmap. Please as a member of the TikiCommunity find your Latitude and Longitude and add yourself to the list. There are links available on the page to help you.
This mapping is current done manually, but we hope that in a future release of TikiWiki we can use the TikiMap feature and include this as a Tiki Feature!
