Help build a public database of UK postcodes

[Howard]

If, like me, you're a fan of the idea of communities building databases (e.g., Wikipedia) it might be useful for Marple residents to help out with an interesting project. New Public Edition maps are trying to create a freely usable UK postcode database. The Post Office owns the database of postcodes and their corresponding coordinates. This means that you or software that you buy can can only use postcodes if you buy a license from the Post Office.

New Public Edition is trying to solve this. They have 1950s-era public-domain maps and they ask you to locate your house (or childhood home) on it and key in your post-code. They do the rest, eventually building out a complete database of every postcode in Britain. The resulting data will be released as purely public domain -- no restrictions whatsoever on re-use.
