http://libregamewiki.org is now back up! The Faiumoni association http://faiumoni.de/en/about.html is providing hosting without ads, and a new spam prevention system allows normal account creation without approval.
We have updated the software and are in the process of bringing the site back to life. We think Libregamewiki is a great project ever since our involvement through our links with Stendhal game - http://stendhalgame.org. We hope to provide a stable platform to help it grow.
