We still want your postcode!
This week, on our sister programme PM we're launching a brand new experiment.
All you need to know is the postcode you're in when you listen to PM. If you're travelling when we're on the air, we'll happily accept your best guess as to your postcode, or the rough location. If you're overseas, try the local postcode or zipcode.
Then just email your postcode to this address: ipm@bbc.co.uk Please put POSTCODE in the subject line.
Don't worry if you don't have email. You can pop it in the post too. Just send a letter or postcard with the postcode you're in when you listen to PM, to this address: iPM, Room G601, ´óÏó´«Ã½ News Centre, London W12 7RJ.
In PM tonight, Chris - Mr Blog - pointed you towards several handy mashups: Try , and this!
