Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.

MediaWiki has a special language called wikitext to make editing more easy. This language is supported in visual mode and will not break as easily as html.

You can also enter source mode when creating or replying to threads in a forum, or when using a message wall by clicking underneath the edit area.
