Why the Submissions page is accessible for everyone?

1) During activation you are offered the chance to activate cost and contact fields. After activation, you are allowed to change that choice via the BePro Listings->Options admin menu

2) If you don’t know how to use shortcode, read our documentation. There is nothing forcing you to allow non members to submit. In fact, we offer a profile shortcode just for registered members. Its mentioned in the, shortcode builder (in the plugin), here on ww.wp.xz.cn(right on the plugin page) and in our documentation (includes a video explanation).
