I am providing an application (windows application), This application can search in the stackoverflow and show results. Then User can write answer for that Question or write comment for that, Now my problem it when I want to write answer in the stack overflow i have an error it is :

{ "error_id": 403,
"error_message": "Applications must have a registered Stack Apps post to write",
"error_name": "access_denied" }

more over I registered my application before also my access_token it is by write permission value. dose some body have any idea?
