Check out http://www.twistedpromotion.com/forum/ and see the sidebar. Notice the "Top Poster of the Last Hour?" That there is a custom addon. What it does is it displays the name of the top poster over the last hour. It also displays their homepage (they must set first in their profile page). This is beta and very basic. I'd like to improve on it. But what are your opinions so far? Please do share. Please be kind, though. I've had hours of DB errors. I was calling the wrong queries. It was quite tricky.
