If this is displayed without user login, it will allow anyone to submit a directory entry (required moderation). Is that is what is desired? If it is, then you can use the
[connections_form] shortcode on any page which is not password protected.
Please note, if you opt to do so that this method (shortcode) is a legacy feature no longer supported. I have no plans to ever remove it but it may not continue to function properly forever.
Hope this helps!
