As I recently offered my first vote incentive on TGaB, I've been checking topwebfiction.com fairly regularly to see how I'm doing. The other day I pulled it up at work and discovered, to my amazement, that most of the top listings have banner art. No such art ever appeared when I browsed the site at home, and still didn't after I came back to check. Not until I was footling about on TvTropes tonight did I discover what makes the difference: to load the version of TWF which has banners, you have to put a period after .com in the URL.
I have no idea what kind of sense that makes.
Anyhow, I'm late to the party as I didn't realize TWF banners were a thing, so... How do I get one? I can make my own art pretty easily, but how and to whom do I submit it? I didn't find any relevant links on TWF itself, but it does say it's offered as a service of WFG. Anybody know?
