I want to stop getting so many notifications / I want to remove myself from your mailing list.
How do I turn off the Notifications sounds?
You can do both of these by clicking on the little person icon next to your name (this is at the top of the forum). This will take you to your notifications control panel also by reading this article.
In the Notifications settings there is a heading that says "Notifications Preferences". Uncheck "Play a sound when I receive a notification".
