GoZips,
Can you give us some detail on what you were doing when it lost your post?
Did you hit the back button to go back and edit?
After it disappeared, what showed up on the screen?
Unfortunately, I do think the post is unrecoverable on the server side since it never made it to the board, but if you can give us some more specific information as to what exactly happened, and what you saw after it happened, I'll be better able to prevent the problem in the future.
Thanks for posting,
Zippy.
