New website
The MPD website has been relaunched. Wikia has been hosting the MPD website for a few years, but Wikia turned out to be an annoying experience for many visitors. Lacking a real maintainer, the wiki grew into a confusing mess over the years, making it harder and harder to find the answer to a given problem. The goal is now to move helpful information from the old wiki to the user manual (which nobody knew it existed).
The new website is being managed with nanoc (LWN article). If you want to help, clone the git repository and send a pull request. The user manual is managed in the MPD git repository.
