* Publish changes.
* Optional: Go to the Talk page and explain what you've done, and why.
[[Wikipedia:Administrators|Administrators]] and other editors who have been granted access to the rollback feature have additional links that:
* appear only next to the top edit
* revert ''all'' top consecutive edits made by the last editor
* work immediately, without the intermediate confirmation diff page
* add automatic [[Help:edit summary|edit summary]] "'''m''' ''Reverted edits by [[Special:Contributions/Example1|Example1]] ([[User talk:Example|talk]]) to last version by Example2''", marking edit as minor
Rollback links appear on the [[Help:user contributions|user contributions]] pages, [[Help:Watching pages|user watchlists]], [[Special:RecentChanges|recent changes pages]], [[Help:Page history|history pages]] and [[Help:Diff|diff pages]]. Note that in the last case, rollback links can be misleading, since reversion is not necessarily to the old version shown (the diff page may show the combined result of edits, including some by other editors or only part of the edits the rollback button would revert). To see the changes the rollback button will revert, view the specific diff that compares the last version from the last editor with the last version from the previous editor. Users with Twinkle enabled will also have three buttons which works similar to rollback, but each is used in a different situations;
Rollback AGF is used to revert good-faith edits, so an edit summary is required.
The standard rollback allows doing mostly the same thing but with an edit summary.
The vandalism button should only be used to revert obvious vandalism, since it only takes a single click and does not require an edit summary.
The rollback button will look similar to this:
[<nowiki/>[[wikipedia:Rollback|rollback: 1 edit]]]
Rollback works much more quickly than undo, since it:
* allows reverting without even looking at the list of revisions or diff
* does not require loading an edit page and sending the wikitext back to the server
* does not require a click of the Publish changes button
On the other hand, it is not as versatile as undo, since it does not allow specification of which edits have to be undone. One may want to revert more or fewer edits than the rollback does or edits that do not include the last edit. It also does not allow adding an explanation to the automatic edit summary. Rollback may only be used in [[Wikipedia:Rollback_feature#When_to_use_rollback|certain circumstances]]; most commonly to revert [[WP:VANDTYPES|obvious vandalism]]. Rolling back a good-faith edit or even during an [[Wikipedia:Edit warring|edit-war]] may be interpreted as "I think your edit was no better than vandalism and reverting it doesn't need an explanation". The rollback right can be revoked on misuse: refer to [[WP:Rollback|its main page]].
If someone else edited or rolled back the page before you clicked the "rollback" link, or if there was no previous editor, you will get an error message.
In cases of flood vandalism (rapid changes to many articles), administrators may choose to hide vandalism and reverts from [[Help:recent changes|recent changes]]. To do this, add <kbd>&bot=1</kbd> to the end of the url used to access a user's contributions. For example: http://en.wikipedia.org/w/index.php?title=Special:Contributions&target=SomePersistentVandal&bot=1.
When the rollback links on the contributions list are clicked, the revert and the original edit that you are reverting will both be hidden from recent changes, unless you click the "bots" link in the Recent Changes to set <kbd>hidebots=0</kbd>. The edits are not hidden from contributions lists, page histories or watchlists. The edits remain in the database and are not removed, but they no longer flood "Recent changes". The aim of this feature is to reduce the annoyance factor of a flood vandal, with relatively little effort. This should ''not'' be used for reverting a change you just don't like, but is meant only for massive floods of simple vandalism.
