I'm most active on StrategyWiki, but when I'm here I'm working on improving the PD Help pages. The info there is great but quite a bit is incomplete or no longer applies to active MediaWiki releases. I'm also adding various things I've learned about MediaWiki (often the hard way).
I worked on the MediaWiki Administrator's Handbook over on Wikibooks a while back, so if I remember to I'll eventually integrate some of the advice from there into the pages here.
make improvements to Help:Navigation update Help:Tracking changes to cover enhanced changes
- update Help:Preferences to explain the rest of the functions
- look through other pages at Help:Contents
- check that pages in Category:Help are also linked to by Help:Contents
- ask someone in the know about the copyright status of screenshots of MediaWiki interface elements
