As a user,
When I learn that https://en.wikipedia.org/wiki/User:DannyS712/Echo-whitelist controls customization of my notifications
I wonder if other users should be able to edit the settings
Its not a very widely used feature, from what I've seen, but Special:MyPage/Echo-whitelist overrides MediaWiki:Echo-blacklist to show notifications from otherwise blacklisted accounts. Given that this isn't stored as a preference, but rather based on the content of a page, should other users be able to edit the setting?
