Seeing as how it was you that asked Nimrod 🙂 I've sorted out Streetmap links. They seem to be the only outfit that will give a good map off a northing and easting.
One each mine details page, under the grid reference (right hand side) you'll now find a Streetmap.co.uk logo and link.
I'm still looking into Microsoft Live maps though; either embedded or linked in the same way as the Streetmap.co.uk map.
my orders are to sit here and watch the world go by
