Editing Help:Edit summary (section)

===Fixing===
After you publish the page, ''you cannot change the edit summary'', so be careful with it, particularly if you are in a heated content dispute&nbsp;– do not write things you will regret.

If you make an important omission or error in an edit summary, you can correct this by making a [[Help:Dummy edit|dummy edit]] (a change in the page with no visible effects), and adding further information in the dummy edit's summary.

In the extreme case of an edit summary containing certain kinds of harmful content, the summary can be deleted on request. They may be removed from public view by [[WP:ADMIN|administrators]] using [[WP:REVDEL|revision deletion]]; such edit summaries remain visible to administrators. In even more limited circumstances, the entire edit may be [[WP:OVERSIGHT|oversighted]], leaving it and its edit summary visible only to the handful of users with the Oversight permission.
