bruceq I'm curios what your source is. You said the current holder of the record is Amnesty International. However that is an easy thing to verify. Unfortunately Amnesty International only hold 2 Guinness Book Records. one is for "Largest Human Rights Organization" and the other is for "Largest Book of Signatures". The printed findings of Amnesty International have been used in 7 other world records, none of which, have anything to do with letter writing. Further to that point i was unable to find any world record for "letter writing", "letters written", "letters mailed", "letter-writing", "letter writing", or a dozen other variations i tried. I did find one entry under "writing letters" but it was for Smallest Nano Calligraphy. I sincerely doubt there is a way of clocking the number of letters written in that manner accurately. I'm going to refrain from circulating this without verification.
