What is more satisfying than successfully helping somebody? Just about nothing ...
Well, Sproggy and omskates beat me to it. That was beautifully said, longtom. And it encapsulates why any one here on the forum would want to go out of their way to help a perfect stranger solve a problem. Even a frustratingly difficult problem. It isn't for fame or recognition or financial reward. It's the deed itself that provides its own reward. Why else would we do it?
@jimwilk,
I've seen the agressive attitude in posts you speak of. I don't have the responsibility of being a moderator, especially a low-down, mean and nasty one like old-polack!

But, I have taken such posts as a personal affront before, because we all help make this community what it is. And this is
the best one I have ever seen or been a part of.
I just wanted to touch on a point OP brought up. Often, when I see a poster asking for help, and the poster has only one post, I wonder whether we are being egged on. I wonder if it's someone who has "invented" a problem in order to waste forum members' time. It's hard to judge the sincerity of the poster, because so many of them just
don't include anything specific in their post. It seems as though the first half of some threads are spent just trying to squeeze information out of the person seeking help.
For me, the most frustrating part is deciding whether the request for help is real or contrived. I don't have enough knowledge and experience (and probably never will) to be able to help in all sections of the forum. So, I sure don't want to waste my time on someone who is just pulling our collective chain.
Okay, I've said it. My illustrious two cents' worth.
