@JWolf: I'm just using the system that has been used here for quite some time now, and for the purpose of what I want to try to achieve, filling up the ranking site, it has to be done that way. (What you propose would mean a lot of work not only for the poor soul who would have to repost the threads, but for the moderators, would flood the board with "old news" at the risk of drowning out current discussion and would have the heavy downside of losing many votes)
@Zarkon: Thank you for your comments.
BTW the review thread for The Belly of the Beast
has been posted.
