Note: Some users may have to wait up to 24 hours for the new Wiki site to appear. This is due to the fact we changed the IP address of the Wiki site and it takes time for cached DNS entries around the world to notice the change. If you still see the ugly slab text page with "wiki returning soon" messages, then you just need to wait a day. Sorry for any inconvenience!
Note2: If you are still seeing the slab text pages, you might be able to see the Wiki site sooner if you ctrl+f5 (force full cache reload).
We are now running the latest version of MediaWiki, as our new Wiki host is much better about keeping it up to date. The old host was stuck about 5 versions behind. They were.. not so good.
