draw a circle around a point

I think it would be very handy for planning sake to be able to draw a circle of a known radius around a point on the WS map. For example if I wanted to do 60 mile days than I could draw repeated 60 mile circles and see if there were any hosts near the edge of my circle. There are circle drawing tools for google maps it just would be handy to have them on the WS map. Thanks for all the work on a great site. dtb
