I suggest us to use Wikipedia's Section guidelines when formatting articles. This would force the articles to be clear and easy to understand.

Also something useful/interesting for graphs, etc: How to keep image file sizes as small as possible.

Also: http://en.wikipedia.org/wiki/Wikipedia:Graphics_tutorials

Simplified guide with the most useful things IMHO: http://www.rarewares.org/wiki/index.php/Help:Editing

I agree with this 100%.

Once the wiki policy becomes more defined, this kind of thing should be emphasized a lot more.

I created a stub template based on wikipedia. To use it just add the {{stub}} tag at the end of the documents.

Stubs are used to track documents that are still poor in its contents.
