Sometimes posts do get lost in the cyber ether. Unfortunately we don't know why it happens as all things seem to be OK when they are checked out.
Depending on which browser you use, you may be able to use the back button to go back to it. Mozilla FireFox and Google Chrome keep the history in them whilst you still have the browser open. If you shut it down and reopen it tho, the history is gone. Unfortunately, if you're an Internet Explorer user, you can't go back thru the browsing history as, altho it will show, when you go back thru the history, a message saying that the page has expired is shown.
f you can't recover what you originally posted, then the only thing you can really do is retype your intro I'm afraid
