You can edit/delete your own posts by hitting the edit button. They seem to be time sensitive. I could delete this post shortly after submitting it but when I revisited my post from yesterday the delete option was gone.
I'm surprised anyone actually had time to read my post. It was up for all of thirty seconds. Just enough time for me to read Rob's entry and realize that my quick wit was too slow. Fear not though, I've always got one chambered.
