A "Suggest for Wiki" button/link could be neat. Basically, if someone reads a post (or thread?) that they find important in the context of lasting reference material, they flag/vote/mark it. Not sure where that goes, but could make for a good "triage" list where volunteers could sort/refine/filter. Not sure if this is the right idea, but we need *something* to encourage promoting the good content that often gets buried in a few days after being posted.
