The right column seems like it's forum specific, so why not call it something like TPR Roundup or something like that (I know that sounds like the MiceChat thing, but, y'know, i"m none too creative)
"Top Forum Threads" "Favorites from the Forum"
Also the little white message before the update columns seems kind of non-sequitur... A simple message about why you should join the forums. Maybe make it the same as the Save the Date! thingies above it, with the small picture being a screen shot of the mySpace or something... You don't really need to bump the forum since most everyone in the coaster community already knows about them! And if they don't, all the great threads that're linked below already give them a solid gauge of the awesomeness to abound.
And the empty chunk on the right column could be eliminated by either A) Making the Special Features section centered or B) Putting older topics up there...
