I've noticed, as of late, that there is a ton of SPAMbot posts to this Message Board and the webmaster's deletion process/method may have deleted your post in error. And if so, there is no real way of looking back to see if that was the case. As I recall, some of the techniques being used on the Greg Susong Message Boards are also being used here, which includes some very strict (narrowly defined rules) that are automated and while remote, your post may have succumbed to that filter.
Your best bet however is to just make the post again.
