We’ve just improved the wiki … again:

• Update to MediaWiki 1.17. This has fixed copy-paste bugs in the wiki editor – which now works perfectly
• We’ve made it easier to find non-English translations by adding Wikipedia-style Inter-language linking. This means that you can find out the translations of a page from the sidebar as shown (see Help:Translating Wiki Articles and Help:Language Policy for more information) 
  
• Now you can add arbitrary line numbers to your code snippets (see Help:Code Syntax Highlighting). 
  
• You can see the full list of fixed defects in our Community Help And Support Bug Tracking.

We’re also working on the content, adding ArticleMetaData to make it easier to work out whether an article is relevent and up to date, and reviewing the updated articles to track and fix basic errors.  You can join us in the review project if you want to help!
