From Wikitravel

Redirection pages are pages that automatically link to another page. You may want to have a redirection page for any of the following reasons.

• There are different ways of writing the article title, but only one article,
• The article is in a different namespace.
• The title has been misspelled,
• Two articles have been merged into one,
• The page might become a disambiguation page in the future, but there is currently only one article,
• The paged has been moved using the move page feature.

Format

The following text should appear in the edit window.

#REDIRECT [[Target_article_title]]

Effect

When a link is followed to the redirection page, the user is delivered the page contained in the REDIRECT link instead.

Troubleshooting

Redirection pages cannot be concatenated. If there are 2 REDIRECT links in a row then the second redirect page will be delivered to the user. The solution is to go back to the original page and fix the offending link.

The offending link should have the [[redirect page title]] changed to [[Target_article_title|redirect page title]]

The Special:BrokenRedirects page lists broken redirection links.
