Good Style es una página que indica las buenas maneras a la hora de usar un Wiki:

-Write factual information.
-Give concrete advice.
-Use the ThirdPerson when possible, as this makes editing and elaboration easier.
-Write and sign first person accounts when reporting experience not easily reduced to facts or advice.
-Place words where they are easy to read, which isn't always at the bottom.
Edit pages to emphasize the flow of ideas, not the chronology of contribution.
-Be concise and stay OnTopic for the page.
-Use language you'd be comfortable reading out loud - use vs utilize - and keep it simple. Simple language often communicates better.
-The server has very simple TextFormattingRules. Start each line without spaces and separate paragraphs with a blank line. You can run capitalized words together to make HyperLinks.
-Use horizontal separators to make things easier to read. When there are lots of different comments with no separation, they can get confusing.
-Edit only when you think a page is lacking - don't just sign your name at the bottom of every page.
