Congrats TH. As stated (by both yourself and others) a truly EPIC number.
Going by my calculations that is an average of 3.8 posts per day over a 3 1/2 year period and that is EPIC sustained effort so well done Sir!
5000 posts / 1317 days (10/08/09 to 18/03/13) = 3.7965
Please give us an updated catalogue of your FJ items because they must be seriously racking up by now!
