The thing that makes this a "Wiki", and not just a collection of editable pages is the ability to create "links" between pages. In the "classic" formatting, a link is identified by creating a "WikiWord"; placing two or more initial-capitalised words together, CamelCase-style (e.g. {{HomePage}}). If the page exists, you'll see a link to it, if it doesn't exist yet, you'll see the name in red, which you can then click to create the page.

Note that differences in capitalization are irrelevant between two identically-spelled {{Wiki Word}}s: HomePage and HoMepage link to the same place. This does not make the latter any less ''[[TheProblemWithPenIsland wrong]]''.

In addition, punctuation is not allowed in [[WikiWord Wiki Words]]—it appears automatically after edits have been saved. See [[http://tvtropes.org/pmwiki/custom_title_request.php The Custom Title Request Tool]] (also found on the main page sidebar) for instructions on creating a new page whose title needs punctuation and Administrivia/TextFormattingRules for specific details about the format.
