This thing is implemented into the PEEL main page. As far as I know it has to be set manually. This means that mArc - who got a life of his own, a job to do, a girlfriend to entertain and to run at least 2 futurama webpages - needs to pay even more time on changing it. More time than he already spends here with banning and unbanning idiots, deleting spam, and fixing bugs and errors in the database. In short, why in hell should it be changed? It is just a link to an episode thread and a poll about it. Something regulars, like you want to be, can easily look over and ignore.
In short: It won't change due to the lack of priority and time.
