I've been working my way through the item pages adding in code to embed their mouse over details. I'm happy to work my way through all of those alone (more than 1 person we'd probably trip over each other) but it would be good to get some activity elsewhere. I've listed below a few pages I came across last night that could definitely do with a going over.
These are all single pages so they are finite projects, you'll not be opening a can of worms with categories etc so they're easier to manage. Bit sized projects
Crafting - There's new UI images and images of the 3 artisans could do with being added. A read over of the text too to ensure it's still accurate. It's not been touched since 27 Aug so I'm betting there are bits that need refreshing.
Randomization - This hasn't been updated since it was created but now we have some actual examples of the randomization in D3, what is and to what extent and what isn't randomised.
Diablo 3 Basics - This definitely needs a read over to make sure it's current. It's the one I send newbies to (it's my signature too).
Diablo 3 FAQ - This is the official one which should have been updated by Blizzard by now so our copy of it needs updating. The old 2009 one needs archiving just like the 2008 one was which you can see linked at the top of that page.
Any of the existing updaters or new people looking to get involved in DiabloWiki.Net but not sure where to start, something in the above list may stoke your fires.
Any queries feel free to post them here or PM if you'd rather.
