Notifications (formerly Echo) is a web service designed to inform users about new activity on Wikipedia in a unified way. It provides notifications to users of a number of events related to their account, including new talk page messages, edit reverts, mentions or links.


It is intended to augment (rather than replace) the watchlist, by highlighting key user interactions.

Notifications are displayed next to the username and user-talk links in the top right of the page for logged-in users, displaying a red square with a number representing the number of recent notifications. Email notifications can be set up for some or all types of notification as a user preference.

Notification messages

You can find your recent notifications not only by clicking on the red message box on the top right of every page, but also in a special archive containing your recent notifications on one page: Special:Notifications. For other tips on how to use this tool, visit this FAQ page or this testing page.[clarification needed (Is this last page deprecated? Should it be deleted or moved to See also?)]

Triggering events

Notifications inform you of new activity on Wikipedia that concerns you

As of November 2014, eight types of event trigger a notification message and increase the notification number by one. You can customize which notifications you receive by turning each type of notification on or off individually at the Notifications tab of your preferences.

You can also trigger notification messages for another editor by mentioning that editor's user name in those of the following events to which you have access.

  • Talk page messages: When a message is left on your user talk page. This replaced the full-width orange banner stating "You have a new message from another user", but by default a small orange tag will be displayed next to the notification to highlight it.Talk page messages are the only type of notification which cannot be disabled; a web notification will always be sent.
  • Mentions: When your user page is linked to on any talk page or on a page in the Wikipedia: namespace by another user. A number of templates are used for this - {{U}}, {{ping}}, and {{reply to}} - will all trigger notifications. Plain links to user pages will also work: [[User:Example|]]. This is one of the most popular uses of notifications; it is often used to inform other people about ongoing discussions of interest to them, or to let them know of a reply to a message on a page they may not be watching. Registered users can be notified by other users and by IPs, however, an IP cannot be notified in such a manner. Note that the post containing a link to a user page must be signed; if the edit does not add a new signature to the page, no notification will be sent. It must also be in the page text—links in the edit summary do not create notifications. More details are available at mw:Help:Echo#Technical details.
  • Page links: When a new link is made from an article to an article that you created.
  • Page reviews: When a page you created is reviewed.
  • Edit reverts: When one of your edits is reverted by another user.
  • Thanks: A small "thank you" for an edit, made by another user from the article's Revision history page or one of its Difference between revisions pages (aka diff pages or diffs).
  • User rights: When your user rights change (as of November 2014, this does not include gaining autoconfirmed status).
  • Course talk: When anyone posts to the talk page of an active course page you are participating in.

Blacklist and whitelist

There is a site-wide list of accounts that cannot trigger notifications at MediaWiki:Echo-blacklist which can be overridden by users at Special:MyPage/Echo-whitelist. As of November 2014, it contains one entry; SineBot (talk · contribs). SineBot adds signatures (including linking to usernames) of users who don't sign their posts; if it were able to trigger notifications, it would be notifying hundreds of people daily without real benefit. If you wish to be notified that SineBot has signed one of your posts, you can whitelist it.


If you mention more than 50 users in a single post, then notifications for mentions will not be sent to any of the users in question. This is done to protect people against possible spamming.

Known bugs

There are a number of bugs currently known with the notifications system:

  • Failure to spot signatures. In some cases (usually when changing another, recent, comment with a signature) the parser does not realise that a user has made a new signed comment, and so does not trigger a notification. The technical requirements for notifications to work are described in mw:Help:Echo#Technical details.
  • Confusing section titles. On pages with complicated markup, or after edit conflicts, the notification will sometimes give the wrong section heading for a message.
  • Transclusion. Because a notification is generated whenever a page is linked to, accidental transclusion of other pages can cause a sudden flurry of unintentional notifications through links on the transcluded page.

For all open Notifications related bugs, see the list on Phabricator.

History and on-going developments

This tool was developed by the Wikimedia Foundation's editor engagement team, originally under the name "Echo", and was released on the English Wikipedia on 30 April 2013 after extensive testing on For more information on the development of Notifications and its features, see this Wikimedia blog announcement and the editor engagement team's Echo FAQ page.

The team plans to develop a few more features and notifications, based on community feedback. The editor engagement team expects this notification tool to be an integral part of future engagement projects, such as the upcoming Flow messaging feature.
