If you do it like the servers section, where there's one section that's moderated normally and one with a `contact registry' where everyone moderates their own entry, I could see it working. Maybe you could try it for a week or so and see how much it gets abused.
Any other set up would probably be horrible.
And I think a `flame' or `spam' board would be a good idea. Even if there is no `flame' board, I want a spam board, where I can post at length about my metal cheese grater (and how smoothly it slices through that yummy cheddar) without fear of a ban or deletion.
@Rocinante: However mature you think you are, there are people who aren't so mature. Since you take care of this forum, you should care whether or not people need/want something, and think about implementing it, even if you don't agree with it (and there is no damage done). Maybe I just don't see things well enough, but it seems to me that there are enough people wanting it to at least think about it.
On a bit of off-topicness: seeing how my permanent ban has expired today, shouldn't Solar's week-long ban expire sometime soon?
