Old posts never die, they just get reincarnated as "recommended reading. I feel stupid. I sent some long elaborate replies to some posts that were years old. CTValley pointed it out and he's right. I didn't check the date, often years back, that these questions came in. Dumb! I don't know why the forum is reviving posts from 3,4,5, and even 9 years back, but it is, and if you plan to answer a question you might want to check the original posting date. I will now.
