Cross-posting (posting to multiple forums) is considered bad etiquette. Effectively, you are being selfish with and inconsiderate of our time. I understand this may not be your intention, but this is how it is often perceived, and the effect is the same. People over at Dev Shed or wherever, may be busy working on answering your question there, when you've already received an answer here. We help people out for free, in our spare time. We have jobs, families, hobbies of our own, etc, etc, and if we answer a question that is already answered, two things happen. First, we are not spending time on somebody else's answer, since we're busy duplicating (read: wasting) our effort on yours. Second, if we knew you were already getting help, we might prefer to spend our time on something else.
Now, there are a few instances where it is acceptable to cross post, and there are right ways to do it. Usually this is when you have a very esoteric, multi-discipline problem, where there simply would not be sufficient expertise on any one forum. The correct way to handle this is, on each forum you are seeking help, to note that you have cross-posted, why you have done so, and to link to each cross-posted forum, so that people assisting you can stay apprised of the progress, and wont duplicate effort. Your situation does not apply, however.
What really irks me, personally, beyond the above, is that cross-posting is explicitly forbidden in our forum guidelines. When you signed up for an account on this forum, you agreed to having read the rules, having understood them, and having agreed to abide by them. Could you imagine telling a police officer you didn't know there was such a thing as a speed limit, or that red lights mean stop? That would be absurd. Just like it's absurd for you to state that you have no idea cross posting is wrong.
All this, on top of the fact that in your first thread over at Dev Shed (
