I hope that the quiz continues - I wasn't even aware that the quiz was there! You see, I generally only check the forum, not the main Marple web pages.
Perhaps you could have a topic on the forum with a link to the web pages when a new entry is posted. Then people who visit the forum and the web page will be able to see there's been an update. In fact, Mark, you could do the same thing with the whole web site by having a topic called "updates to the web site" on the forum showing what's new.
