Number 1 has already been talked about: Tech Support. Some, even me, were skeptical at first, but now many of us are really starting to want it. Maybe Christian can be the moderator.
Number 2 is an idea I just had today for a "DK History" or "DK Milestones" or "Big, Big, Big Moments" forum. This forum would contain discussions, threads, and lists related to the progress of the competition over time.
The Kill Screen Timeline and the Million-Point Timeline would go here. Those aren't quite right for the High Score List forum, but to be honest, I feel like they deserve to be somewhere a little more prominent than Steve's List Forum, which is basically a gag forum. They feel awkward there.
I have some other ideas as well.
First, this is where we would make (and/or move) threads commemorating player achievements, such as breaking a million, or getting their first kill screen, or winning a Kong Off.
I'd also like to have a thread (or several) for older iterations of TG's DK scoreboards, so that we can actually look at how the scoreboard evolved over time. I have several as it is, but I'm sure if we pooled our resources we could track the changes pretty closely year-to-year since King of Kong.
At any rate, I DO think there's enough to work with for a dedicated subforum! I'm not sure what topic it would be nested under (maybe "High Scores"? Or maybe "Other Lists" could be "Other" and it could go there?), but we could talk about that. Or we could just ignore the idea altogether.
