pretty much a confession that you never read the original question.

That's true I didn't (and still haven't) and I didn't respond at the
original posting level, either, did I? *I was prompted by a side remark
somebody else made that jogged another thought...if it doesn't pertain,
well, so be it, I didn't know it at the time. *That there wasn't an
optical sensor on the opener in question wasn't in the subthread to
which I responsed; the mention was not referring specifically to the
specific and it can be inferred as to what "ancient" means by many
different folks having many different interpretations.

Again, hardly seems worth fussin' about; if you don't like/need a
suggestion, go on to the next. *It is, after all, usenet...

I agree with Joe. People just clutter up posts with irrelevant info.
It doesn't help the op. It'd be different if the post starts out as a
discussion but it didn't. It was a specific problem looking for
help. In Joe's case it doesn't matter much cause Joe has other
background info and knows a lot about the topic already. But some
people posting here are novices at the home repair stuff. It confuses
them.
