No. And it infuriates me when they don't. It has for years. But many people post in such a manner not simply because they are lazy (and they certainly are), but because they know some kind soul out there will reply to their post and possibly give them they answer they want without their having to do any extra work at all. In the animal kingdom, we have named such creatures "sloths" and "leeches."
With that said, this site tends to be better than others I post in. CubeOwner.com is about the worst. Dozens of posts each day by people who could easily find the answer in the clearly marked FAQ or by a quick search of the forums. There are other sites too, but I'll spare you.
Ah well... I'm sorry for the rant. Mac128's comment struck a chord in me for some reason today. But I admit my rant is not directly relevant to this thread and I'm sure I've upset some people in the process too. But if any good can come of it, I can only hope it will help to inspire new posters to Search before posting.
