How can I set WordPress roles such that once a Contributor's post is scheduled to be published, they can no longer edit it?


How can I set WordPress roles such that once a Contributor's post is scheduled to be published, they can no longer edit it?



At least for my purposes, it is absolutely essential that a Contributor be unable to edit his posts once they've been scheduled to be published, as well as actually published.

This seems like it should be simple because otherwise in a system with a lot of users a malicious user could slip under the radar with a sketchy post by first submitting an innocuous one and then right before it is scheduled to be published, edit it.

None of the role-editing plugins I've tried seem to have this functionality.

Is there a Wordpress plugin which let the user register/login and see some new elements if he/she logs in?
