I briefly canvased Wikipedia about which site to use for free wiki hosting and then settled on wikidot as having the least commercial bias. I have a strong preference for MediaWiki, as its the industry standard, but the markup is similar enough for wikidot for it to be easy to add content.
I've not mastered categories or templates by any means, and want to have at least two templates: one for people and one for games.
There's extensive entries to be added, obviously, probably by first providing an external link to wikipedia.
My wiki design so far has been borrowed from RogueBasin, but I'm open to suggestions as a relative wiki neophyte.
As for the decision to use free hosting? In a household of laptops, the free hoster is king. or if you prefer, In the country of bandwidth caps, the free hoster is king.
