Thanks for the info and advice.
With regard to how many hits is a fair test, I was wondering about that. I'm terribly new at this -- what is a good rule of thumb for testing a new sponsor? How much traffic do folks usually send before making judgment's about the sponsor's convertability?
Here's the major gallery I've been using to send traffic to The Wasteland. Approximately one in a hundred page viewers is clicking through to the sponsor tour; but so far, none of them has signed up.
