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.
The server has very simple TextFormattingRules. You won't go wrong if you start each line without spaces and separate paragraphs with a blank line. You can run capitalized words together to make hyperlinks. This sometimes requires creativity. Look over TipsForBeginners, especially AddingNewPages.
Finally, don't say things designed to make others mad. Practice civility and understatement. You will reach ten times as many readers even if you miss the ones you want to zing.
