No Chuck....you didn't do anything wrong. It's in the thread where it should be. You can set "preferences" so the index will show you the subject lines from the last X amount of days.....

My comment was on the 25th, yours on the 27th. If your preference is set for 2 days, my comment would disappear from your index after 2 days. Your comment would stay longer, since it was posted later.

If you can follow that explanation without a roadmap, you're a genius! Anyway, I hope it sorta makes sense!
