I have a request - can tables be made less ugly, and/or the big table at the top of the 'Command-line reference' be removed? If people want a list of flags they can always check the launcher.
Duplicate information should be kept as minimal as possible, so that coders or whoever can easily update things in *one* spot without having to run around and update other parts of the wiki. I edited the Download Tools and Modelling pages so they weren't 90% identical information.
Also, style should be paid attention to. Pages should use header tags and such more like this:
!!!Page name
Maybe introduction text?
!!Section
Could be more introduction text
!A sub-section
Look, I'm talking about a specific subject!
!!Another section
!Item
*Description
!Item
*Description
!!Yet another section
!Item
An indent because it just looks so good
!Item 2
Look, ma, more indenting!

Some comments about how the information is out of date, the author was drunk while writing it, etc.

Rather than this:
*The page header
!A section
!!!An individual item
descriptive text
!!!Another item
more descriptive text
This is where the credits go, but it's confusing at first whether they're credits or not because there's long, descriptive text on the same level as the last item and no divider.
Not only is it good and proper, it looks good and organized too.

To be blunt and honest, go look at the pages I've done, I've always tried to make them organized and clear, because my writing usually isn't.

For the command line reference, I spent more than a half-hour trying out different ways to show the information to figure out what way would be best.
And just to be an arse, would it be possible to have an expandable list to the left of the page? This would make it incredibly easier to navigate the wiki.
