Ciarán O'Riordan here. I'm new to Wikemacs.
I heard it's shutting down, but I hope that doesn't happen. I didn't know this wiki existed, and I think very few people did know. MediaWiki is a great system, so I think this site has a lot of potential.
If it really must shut down, then I'd suggest moving the pages to another MediaWiki site. A good candidate is http://libreplanet.org
