As I write, almost 11,000 postcodes have been sent in.
Thank you, if you've gone to the trouble. Remember we want to build a map of where in the world people are listening to PM. We're especially grateful to a listener in China who emailed this morning...and there are lots of other listeners in locations across the planet. How exotic.
From China, Sam wrote: "Love you programme. I listen every day - one day late, of course, because I am in China. Would love to contribute to the programme by telling you about China. My postcode is ... but may be this is not much good in England."
We wrote back to Sam with the same sort of advice we'd give you if you're living abroad, or if you're travelling when PM is on. Give us as much detail about your location as we can. Sam wrote back with his full address and we will put him on our map!
If you haven't done so, please email the postcode of the place you usually listen to PM to: ipm@bbc.co.uk - and put POSTCODE in the subject line. Or send it by post to: iPM, Room G601, ³ÉÈË¿ìÊÖ News Centre, London W12 7RJ.
As I write George and co are audibly busy sorting out the map that we'll post on THIS Blog on Saturday, when iPM is on the air. In PM last night, Chris - Mr Blog - pointed you towards several handy mashups: Try , and this!
More to come, and remember Saturday is not a deadline...so if you know someone who's a Radio 4 listener who's not online but they might want to be on the map...pass on the iPM postal address to them. Here is a small selection of the letters and postcards we've already received...
