Ron;
I do not see any evidence of any removed story. That leaves either yet another Scoop bug or user error. There will be a confirmation on the top of the page if the post went through.
One issue can be not unchecking the "spell check" button.
Sorry I cannot answer your basic question maybe DanB will see this [which I made to "always display"] so you can get an answer.
Sorry you are having problems posting. Near as I can tell it must never have been accepted for some reason. The logs do not show any removed posts recently.
