Where did the wiki GO

I did not use it much, but I thought that BGDF had some documentation pages for starters about various board game issues. By searching the website, I imagine the wiki is on this page:

http://www.bgdf.com/node/2

But there is actually only 4 links that leads to another page, all other links just link to itself. Maybe the pages are still in development but I thought that in the past, there were much more page written than 4 of them.
