Hi, I'm sorry that we could not offer lightning support to you. Since we live in different timezones, and are a small team, it's not possible to respond within minutes of someone posting a query.
Your post on our Facebook page "Can I just ask, where is the config screen? spent an hour looking for it." was exactly 10 - 15 minutes before this one.
I'm sorry if 10 minutes seemed like an eternity to you, the internet has distorted our expectations to having near instantaneous results. At times I suffer from the same frustrations.
As for your query: The configurations screen is called "WP Auctions" and appears on the main WordPress navigation menu that is on the left of your sites backend. You'll find everything related to the plugin available on that menu.
It's been almost 5 years since we released the plugin and so far no one has complained about this, so I'm going to presume that perhaps your eagerness to get started with our plugin did not allow you to see the menu item.
As you can see from these screenshots there is very much a config screen with the plugin: http://wordpress.org/plugins/wp-auctions/screenshots/
Thank you for your feedback.
