The Notifications extension, historically called Echo in code and documentation for sysadmins and developers, provides an in-wiki notification system that provides the user with alerts and notices about activity on the wiki, such as another user mentioning them on a talk page, or an edit of theirs being reverted. Other MediaWiki extensions can make use of Notifications to send their own notifications; Thanks and DiscussionTools are two such extensions.
Installation
edit- The database user must have been granted the "REFERENCES" right for the database. How you check this depends on how you set up the database in the first place. For example, if you used a control panel application, then that interface should provide a way to check and change the privileges of the database user (
$wgDBuser
in LocalSettings.php ). - Download and move the extracted
Echo
folder to yourextensions/
directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Echo - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'Echo' );
- Run the update script which will automatically create the necessary database tables that this extension needs.
- If necessary configure at your convenience
- Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
To allow daily or weekly summary notifications to be delivered by mail (for users that choose that in preferences), the following script inside the Echo extension directory needs to be run on a daily basis, which can be scheduled in a cron job:
maintenance/processEchoEmailBatch.php
Configuration
editIt is possible to use conditional user options to set different notification preferences for new users, without affecting existing users.
See Special:DisplayNotificationsConfiguration for local details.

Architecture
editUsage
edit- Notification negative list / positive list
There are occasionally specific users, typically bots, which perform maintenance tasks that should not generate notifications. To handle these cases, users can be globally blacklisted from the LocalSettings.php file (or InitialiseSettings.php in the case of WMF wikis):
$wgEchoAgentBlacklist = [ 'SampleBot', 'SampleUser' ];
There is also an on-wiki blacklist that can be maintained by the wiki's community. The location of the global on-wiki blacklist defaults to MediaWiki:Echo-blacklist. Individual users can override the blacklist by creating a whitelist. The whitelist location defaults to Special:MyPage/Echo-whitelist. All on-wiki lists expect to receive one case-specific username per line with no special markup or prefixes. For example:
SampleBot SampleUser
- "Mention" option
One of the notification types that this extension allows is: "Notify me when someone links to my user page." It might not be obvious to some users, but this particular notification only works when the person linking to another user's page also signs (~~~~) the post.
After installation of the extension, a new tab "Notifications" is created in a user's Special:Preferences page. Under the section "Notify me about these events", in front of the "Mention" option, the hoverbox states: "Notify me when someone links to my user page." If an administrator feels, that the requirement for signing the post isn't obvious in this help text, it can be modified by changing the text in the Wiki's MediaWiki:Echo-pref-tooltip-mention page.
Terminology
edit- notification - Any individual notice that is delivered by Echo
