Here's a short reminder on the most common formatting rules you have at your disposal. A complete list is available in Creole 0.4 and Elements.

(empty line)        Make a paragraph break. 
----                Horizontal ruler
[[link]]            Create hyperlink to "link", where "link" can be either an internal 
                    WikiName or an external link (http://)
[[link|text]]       Create a hyperlink where the link text is different from the actual 
                    hyperlink link.
[[wiki:link|text]]  Create a hyperlink where the link text is different from the 
                    actual hyperlink link, and the hyperlink points to a named Wiki. 
                    This supports interWiki linking.

*                   Make a bulleted list (must be in first column). Use more (**)
for deeper indentations.
#                   Make a numbered list (must be in first column). Use more (##, ###) 
                    for deeper indentations.

==                  Large heading
===                 Medium heading
====                Small heading

**text**            Makes text bold
//text//            Makes text in italics 

{{{text}}}          Makes text in monospaced font.
line1 \\ line2      Force a linebreak

Don't try to use HTML, since it just won't work.

Use InterWiki links with the : syntax to shortcut frequently referenced pages like google or wikipedia
