The 500,000th post is only relative to the past 6 months on a rolling schedule. One would have to add up all the 4 five boards (miles, dining, travel, airports and archives) to get close and that doesn't inlcude some of the old threads we have from progra,s still to be consolidated and we've got as of now un-registered. FT is about 1.4 million posts total right now and growing as fast as ever.
