I would propose to the moderators that AF447 should temporarily occupy its own section within Pprune - with seperate sub-threads for the main debating issues, general news and a summary; until such a time as the evidence, reporting, speculation and debate of each nuance begin to gravitate towards something conclusive.
That would be an administrative nightmare. The hapless moderators are busy enough deleting posts at random -to busy to take on the additional chores you describe. The closest thing I think you could whip up is an 'announcement post' (which would show up on each page) and would have researched links to Frequently asked questions. Forum software like this isnt really designed for the type of analysis attempted here.. A Wiki- would be a bit better, not really good but good enough to muddle through with a bit of effort and a lot of discipline/moderation. Maybe Pprune could start up a wiki?? Ppruneipedia?
