It'd be nice if the web masters could install
MediaWiki (the same software that Wikipedia uses) so that everything can be kept in one place. MediaWiki is one of the most powerful wiki systems our there for free and it has literally everything we'd need to run a wiki. It's a little more complicated when it comes to adding and moderating wiki content than Wikia however, but skills can be learned.
I suggested this idea a while back on Facebook and it had some positive responses, so I'm completely for the idea.
