I'd like to remove a subscription or at least to delete some of the notifications. Thanks in advance for the info.
There are green unsubscribe buttons on pages where you receive notifications from. On song/translation pages the button is on the right side when you scroll past the lyrics/translation, and on forum topics the button is near the top of the page. By clicking it you won't receive notifications from that page anymore (unless you post a new comment or subscribe again).
