It might be nice to have an option whereby the members of the community could shut down an objectionable thread by voting it closed. This could be allowed on a per forum basis (rather than a global setting for all forums) with an admin defined number of votes needed to close the thread. I thought of this when looking at some of the troll threads here about release dates, IPB vs VB vs XF, etc. - the kind of threads that make the staff look biased if they close them. Having the community vote it closed would send a subtly different message.
