Hi lch,
Very useful wiki, great effort, great job!
Keeping up my own futile attempts at being useful to the community, I have added links from my online interface of the spell/forge database to your wiki. So a description off the spell/item is just one click away.

Something which really interests me is reading what other players think of the spells/items, how they use them and so on. Would you say that this is covered by the "What this is not" section above, or are you open to having a fuzzy area where users can leave hints/use cases for the items? In the main article? The discussion page? A new cool page for each article which you can hack together in no time?
