Help:Automatic edit summaries

Automatic edit summaries are created by the MediaWiki software for certain actions. These summaries appear in  recent changes, page histories, and contributions lists, unless you provide your own edit summary.

Auto edit summaries exist for five different actions, if the user fails to provide an edit summary:
 * Blanking a page
 * Replacing most of a page with other text
 * Creating a new page (the first 200 characters of the article appear in the summary)
 * Creating a redirect
 * Reverting a revision

Also, when you use section editing, the section title will appear in the edit summary box in light grey text between comment tags, and used as your summary unless you alter or replace it.
