I find that the harder I work, the more luck I seem to have.
As it would be a hard job for them to guess or search for a thing if you don't provide any clue. I would also request you to include that clue in the thread description itself without creating another response to it, as that may go unnoticed by the editors or webmasters.
Hope things get going soon.
Sorry for the late response. I could not locate any such thread. Note that as such there is no such thing as a hidden response. It will disappear only if rejected but will never be hidden. Even if points are reduced, the response itself with your name to it remains intact and we can see it. The text of a response is what can be hidden if, say, minus points are given (such as being copied content or spam), but that text is visible to the editors in case we need to check later why the points were minused.
As Anwesha said, it would be best to always give the URL in your thread post itself for quick reference.
