Yes this would be great.
The 'areas/danger levels' and 'tribe locations' maps are going to be separate from this map.
The only way I can see it being all together AND interactive (selecting different layers), is if I install it on a web page and add Javascript code to it. The problem with this is that I do not have a location online where I could put it unless someone knows a website that allows Javascript coding from clients?
If I had access to the Xsyon database, I would be able to add a live feed of active and inactive tribes sorted by last active member using PHP/MySQL... But, that's a tall order lol.
