Thanks for this Chris,

I've just added about 100 addr:postcodes to some of my manor in no time at all. It was mostly pretty easy to identify a good match for and existing building. Then I went back and added a source tag as an afterthought.

Great stuff all round, I''l try to remember to make at trip to raggedred.net part of future mapping exploits.

The postcodes in Codepoint Open are centroids derived from a combination of all the delivery points that share the postcode so are not at all real-world objects.
