In reply to Brett Bumeter.

There was something called "WP Listings" which was renamed to IMPress Listings:

- https://wordpress.org/plugins/wp-listings/

Our plugin is called Listings but we unfortunately (without all the money in the world) couldn't get this domain.

So we are using http://wplistings.com/ and WPListings on Twitter / elsewhere so that it's in a bit better context :)

Beers are on me!
