I thought this might be interesting... i created a map where we can put a pin for ourselves and our printers. if you pin yourself you can do it as locally as you want. so if you just want it to be near where you live just drop it in the neighbourhood somewhere. i used my forum name for my login. and then for the name of the pin i suggested the format: forum username, printer type (eg. original, PB+, PBjr, etc). it might be cool to use the colour coding for the printer type. so if you don't mind selecting the right colour from the below that will help to view the Printrbot World Population.
