Directory – Cant post to it?

Discovered this site yesterday and downloaded my first plugin today.

The directory plugin I want to be a directory part of a main WordPress site.

I have it all installed but the “submit a listing” option which I presume is how the public add listings to the directory apparently has been “Disabled by the site administrator” (Thats me!!!)

I dont know where or how I disabled this function or how to re-enable it

Any help???
