Originally most wikis used CamelCase as a link pattern, produced by capitalizing words in a phrase and removing the spaces between them (the word "CamelCase" is itself an example of CamelCase). While CamelCase makes linking very easy, it also leads to links which are written in a form that deviates from the standard spelling. CamelCase-based wikis are instantly recognizable from the large number of links with names such as "TableOfContents" and "BeginnerQuestions".
CamelCase has many critics, and it was the switch of the large Wikipedia wiki to so-called "free links", words that are put in double square brackets, which encouraged wiki developers to look for alternative solutions. Various wiki engines use single brackets, curly brackets, underscores, slashes or other characters as a link pattern. Links across different wiki communities are possible using a special link pattern called InterWiki
This wiki supports CamelCase AND [[Free Links]] (the double [-bracket way). Your choice.
We also prefer [[Free Links]] here. Please use them and avoid CamelCase now.
