What happened is that at some point, for reasons no one is entirely sure of, the beginnings of several threads disappeared. This happened in most of the sub forums, so scripts, tutorials and other resources were lost as well. There does not appear to be a way of getting it back, though I know that Nathaniel was hunting hard to try and find one. As a temporary measure, can I suggest this.
It happens that the first surviving post is one of yours. Edit it to explain that the beginning of the thread has disappeared, and put your game info and links there - in effect use it to recreate your opening post.
