From PerlNet

Talk pages are a special type of namespace pages, used to discuss changes on the corresponding "main" article or page. All PerlNet articles, personal user pages, policy pages, templates, etc. have an associated talk page (linked as "discussion" in the top menu).

   * Article talk pages are used to discuss changes to the particular article.
   * User talk pages are used to leave messages for particular users. A message box stating "You have new messages" is automatically displayed to a user at the top of any Wikipedia page, until they view their user talk page.

The "discussion" link references a page in the same namespace as the article, userpage, or template with an additional "talk" before the colon separator, for example: Talk:Foo, User talk:Foo, or Template talk:Foo (where foo is a placeholder).

Please sign your discussions with ~~~~.
