I dunno...You nailed it Jeff, that's the double-edged sword that is this forum. It's entertaining, interesting, and sometimes informative! But it's also at times frustrating, folks typing-without-thinking, and wildly speculative.
A skill you'll want when reading threads here, is to recognize speculation and treat it as such. Once you have that skill, the frustration goes down a bit.
One thing we all could do, is when someone asks a question, we could all say "..... I dunno....", but what fun would there be in that?!
Actually, that was kinda fun
