It's a good argument for starting a new thread when you're going to change the subject, and titling it so there's some kind of clue as to the contents. I'm certainly as guilty as anybody for going off-topic, but it often can't be helped. Somebody says something that reminds you of something else, and you poke your head up. That happens again, and again, and again, until before you know it a thread about installing tuners is all about potty-training your newly-adopted ferret. Makes it tough to find things.
Ironically, this very post is taking us down that road again <grin>
