We need someone to take over managing and updating the documentation. We have a new wiki on our site, but little has been done yet to move the FAQ pages to this format. This needs to be done as well as some other pages need to be added such as the TODO, and Howtos on making cars and tracks.
It would help a lot if we had someone who was focused just on documentation, I do it when I can but it takes away from time coding and such. If someone steps up for this of course I and others will help you. That's the whole point of the wiki.
