Hi Mike,
All Admin can do it prevent or allow a User to post.
A User can be made to request permission to post but once that permission is granted Admin has no control over individual posts. You do have the ability to delete a message (or move it to some invisible area to which only Admin has access).
Nor can you edit a User's post to remove offensive content. The best you can do is move an unacceptable post to a "hidden" sub-forum, reply to it and then move the reply (with original text edited) with some explanation from you about why you have done that.
Volunteer Helper - but recommending that users move off the platform!
Once the admin for GregHelp now deleted.
