We should do a study. Again, I started to skip this thread - as Medic8r points out, there are many more helpful than me....then I got curious. This thread stayed on topic for about 3 1/2 pages before Micah spun it off track. So....we had the best derailer discussion some time back - this study could be on how long the average thread stays on track?
