Notification Blacklist/Whitelist
The are occasionally specific usernames, typically bots, which perform maintenance tasks that should not generate notifications. To handle these cases there exists a global blacklist initialized from the wiki LocalSettings.php and an On wiki blacklist maintained by the wikis community. The location of the global blacklist defaults to Mediawiki:Echo-blacklist. Individual users can override the blacklist by creating a whitelist. The whitelist location defaults to User:Username/Echo-whitelist. All on-wiki lists expect to receive one username per line with no special markup or prefixes.
