I was thinking I could throw up a mediawiki installation with a suitable domain name if the community would find that helpful. It would be professionally hosted (i.e. not by me!) with a 99.99% uptime, unlimited bandwith and I have about 39.9GB free space left with my provider (which should be way more than we need). That way we should be free from the limits of the likes of Wikia and all the advertising spam.
That would be wonderful. We need a wiki.
