It was more than just docuwiki being slow - it lacked some features I wanted, too. Like I don't think you could include files, or parts of files. There's a lot of content I'd like to have in the wiki, and it would be nice if it were easily reusable and handled a lot of things automagically. I don't want to turn down efforts to help, but at the same time, I don't want to get stuck with something that we'll have to abandon down the road due to lack of functionality or something that requires a lot of extra effort for tasks that are automated with alternative solutions. The reason I keep leaning toward mediawiki is because it has a huge amount of development behind it and has undergone rigorous testing with massive sites like wikipedia.
