Just because a question falls off the first page does not mean that it will not get looked at or answered. Most of us heavy posters look at least a few pages deep for unanswered questions.
If you have no replies to your question, and it has been at least a few hours, and your question is at least a few pages deep, then you are permitted to bump up your question by replying to it yourself. So people do this simply with the word "BUMP" in the reply. This will bring it back to the top page.
