Thanks! I don't have banners yet, only skyscrapers, but I could make them. What size?

I suspect you overestimate the number of readers I'd get from FurAffinity, though. The conversion rate from adverts to clicks is generally low, and the conversion rate from clicks to readers is also quite low. That's just the way advertising works. Still, I'd probably get more than zero readers, and that'd be a good thing.
