You've hit the nail on the head. Just do a little research, and if you can't find what you're looking for (even if it may be there somewhere), go ahead and post. I've resurrected old threads, and asked questions that have been asked before.
Most forum members are good folks, who will gently lead you in the right direction if you're off course. However, there are some who enjoy throwing stones at anything and everything.
Bottom line - use common sense and let some of the comments roll off your back. If an honest question elicits a strong response, it's probably not the fault of the OP. Treat this place like a conversation you'd have with a friend.
