I was just turned on to this phenomenon (or shall we say, "movement") called warchalking, where computer users would scour a city with their laptops or other wireless devices, and find "open" wireless networks. If someone happened upon an open network, they would mark the location with a specific symbol in chalk or something similar... some say this is theft (Nokia, for example), while warchalkers argue that it is perfectly legal. Some say that it can be used by folks who want to identify their network as open or closed, by including the symbols in the name of the network...

Are there any "warchalkers" in this forum (most likely there are)? What is everyones take on it?
