This is my Glossary. There are many Glossaries like it, but this one is mine.
Namespace: A way to classify pages. Wikia has namespaces for the main content, pages about the project (which on many wikis will be in the main namespace), user pages (User:), special pages (Special:), MediaWiki pages (MediaWiki:) and talk pages (Talk:, Wikipedia talk:, and User talk:). See also Help:Namespace.
Wiki Markup Language: The symbols, syntax, and functions of MediaWiki products, especially as used in a Wikia, or other WikiMedia projects. See also Help:Wiki_markup
