I started one ages ago, but it looks like I forgot to link to it in my thread https://maps.google.com/maps/ms?msid...579,158.027344 It was originally linked in another thread, which disappeared. No wonder hardly anyone was signing up! I had a better approach than that thread..... I explained all my ideas in detail in that thread, but then that thread disappeared Oh well, at least this idea has got some kind of momentum again, better than nothing! If you want I can totally delete/remove the map I started.
