The end all be all site idea
Okay, here you go...
You add an option called, "classic settings," in which case the forum(s) goes back to the original Mr. Crank style. Whether you want to combine all 5 forums with the review or leave them separate is up to you. I'd just combine everything in order of the date/time it was posted and then start a new one every week. Obviously the user should be able to switch back and forth from Classic Settings to New and Improved Settings. You could even monitor how many users are using what setting, so you'd know what is prefered.
For good ol' days posters who return, the classic settings idea should be prominant enough so that they know they have that option.
