Help:Reverting

 Reverting is the ability to return a page to its previous state. All versions of a page are stored in the history of a page, so it is easy to revert a bad edit and return the page to its previous state.

Step by step
All users have the ability to revert to a previous version of a page.

One edit reversion
If you would like to undo just one edit you simply need to:
 * Go to the history of the page
 * Next to the edit summary is a link that says Undo, click on this and you will be brought to the edit window, which shows the difference in edits on top.
 * Leave an edit summary and then hit save, and the edit will be un-done.

Multi edit reversion
This allows you to return to a specific version of the page, undoing multiple edits.
 * Go to the history of the page
 * Click on the time and date of the earlier version you want to revert to.
 * Then when that page comes up, you'll see something like "(Revision as of 23:19 Aug 15, 2002)" below the title.
 * Verify that you've selected the correct version, and click to edit the page, as you would normally.
 * You'll get a warning, above the edit box, about editing an out-of-date revision.
 * Important: in the case of vandalism, take the time to make sure that you are reverting to the last version without the vandalism; there may be multiple vandal edits.
 * Once you are sure the revision you are looking at is good, save the page. Be sure to add the word "revert" to the edit summary (often abbreviated as "rv"). On some wikis it is common practice to mention the date/time of the version of the page that you're reverting back to in the description as well.

What is rollback, and how do I use it?
Administrators, Content Moderators and users with rollback rights have an extra "rollback" link on history, diff and user contribution pages that lets them revert vandalism faster, without the extra steps of going to the page history and opening an earlier revision. The feature is especially useful in the case of a known vandal, whose edits don't need to be checked before being reverted.
 * Clicking on the link reverts to the last edit not authored by the user concerned. An edit summary will be added automatically stating that a reversion was made, and the edit will be marked as minor.
 * Only use this for reverting vandalism. It should not be used to revert an edit that you merely disagree with.
 * If between loading the user contributions page and pressing rollback, someone else has edited or rolled back the page already, the message "Rollback failed" will display with an explanation of the problem.
 * If the page has been created by a malicious user and nobody else has edited the page, clicking the rollback link gives the message "Cannot revert edit; last contributor is only author of this article". In this case delete the page, or replace the content with something appropriate to the page name if possible.

Can I hide flood vandalism reverts from recent changes?
A "flood" occurs when a vandal makes edits to many pages very quickly in an attempt to make the recent changes page unusable, by filling it with their own nonsense edits (and the reversions which fix the damage). In these cases, admins can choose to hide vandalism from recent changes. To do this, add ?bot=1 (or &bot=1 if the URL already has a question mark in it) to the end of the URL used to access a user's contributions. For example, http://community.wikia.com/wiki/Special:Contributions/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 the default recent changes display.

This means that they will be hidden unless you click the "show bots" link on the Recent changes page (to set hidebots=0). The edits are not hidden from contributions lists, page histories or followed pages. 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.
