It IS a good idea, but it's besides the point, as neither of you is
even trying to answer the poster's question. Why is that? I'm not
being a smart-alec, I'm just curious as to why you both feel compelled
to reply with a non-sequitor instead of actually trying to help out
the poster.

Because this isn't the "fix my house" helpdesk. It's an online
coversation
between a few hundred people with a nominal interest in home repair. And
like any other conversation, it wanders. When people start PAYING
for advice, then they've got reason to expect people to stay on point.
