Got it,
It’s quite nasty but it gets the job done:
1. edit tdo-mini-forms/include/tdomf-form.php
line 987 "post_status" => 'publish',
to
line 987 "post_status" => 'private',
2. edit tdo-mini-forms/tdomf-form-post.php
line 163 if(get_post_status($post_id) == 'publish') {
to
line 163 if(get_post_status($post_id) == 'private') {
It would be nice to be able to change it from the admin panel though.
