one additional thing.
I just spoke about this in irc
we have currently posts throughout the forum with Thanks attributed to them
now of course, some might just be w000t yeah calls and silly things, but what if we did something like slashdot.
the normal view of tmo forums was in a moderated mode and only showed thanked postings in the threads.

nice and simple (theoretically) it should just be changing the sql from all posts to all posts with thanks.

it would be a really easy way to see if the forum would work with moderation and could be done without ny new data structures being added (initially) or changes to the normal way we work.
