Text starting in column 1 or more is formatted using fixed font.
Text placed between <pre></pre> tags is treated as "verbatim" and left unformatted.
A URL coded "bare" becomes a link based on its own text:
A bare URL for an image of type gif, png or jpg becomes an inline image:
A URL like:
[http://www.imbe.net/wiki LIGO SysAdmin Wiki]
Comes out as:
And without the text it becomes a reference:
[http://www.imbe.net/wiki] turns into: 
URL's placed inside of [] (double square brackets) become references to internal Wiki pages that look like Foo?. Clicking on the ? after saving will present you with a virgin Edit page, so that is how you create new Wiki pages!
Do not use spaces in internal Wiki links, use underscores instead, or the search mechanism might not work on your pages!
The [] syntax also supports a "preferred string" form: [[Foo|Foo is the primary metasyntactic variable]], where the string after the | becomes the link text.
"Subpage Links" are supported. If you have a page called "Meetings", you can have subpages with names like [[Meetings/January-01-2008|January 1, 2008 Planning Meeting]] to organize the minutes of all your meetings.
If something in your text is treated as a link and you don't want it to be treated as a link, put it between <nowiki></nowiki> tags!
So, '''foo''' or <b>foo</b>will show as foo.
Italic text is created using the HTML <i> tag OR by using the wiki '' delimiters.
So, ''foo'' or <i>foo</i>will show as foo.
And '''''foo''''' or <b><i>foo</i></b>will show as foo.
This particular wiki also supports the <tt></tt> <u></u> and <strike></strike> tags for monospaced, underline, and
:foo ::foo :::foobecomes
*one **two **three ***four
#one ##two ##three ###four

Colors are defined by matching <color></color> tags. Supported colors are red blue green purple brown orange and yellow.
Since I needed them, <br> and <center></center> are also supported...
as is the color <white></white> for doing visual layout.

And we also support the full html table spec:
A reference to an uploaded file will become a link for most file types, but if the uploaded file is a supported image format (jpg, gif, or png) it will be rendered in place as a link to it's actual URL. In this example, the upload link text is upload:katamari-prince.gif :
It's The Prince!
