Thanks for getting back to me so quickly.
The link to the submission form is

As far as im aware, you dont need to be logged in to submit.
As way of further background, we have inherited this site from a previous
developer and have been the process of upgrading and migrating it to a new
server. Our concern is that there has been some custom dev in the
background, as we have found for other features, but cannot seem to get
anywhere with this one
thanks again
