I'm using this plugin and it seems to work as advertised.
But I have an issue. Whenever I update a post and resubmit the form - I don't get a new post - this is good and what I want - But I get the status of the original formed changed to "pending". Ideally I would like to be to just "update in place" as occurs in the admin page for editing posts. Lacking that, I would be satisfied if the updated posts are left as "publish" as the were originally.
