How do I turn on/off notifications for a thread?
To disable notifications for specific threads, hover over your profile picture, and go to 'My watched threads'. Select the checkbox to the right of the threads you want to turn off notifications for, scroll to the bottom of the page, and in the 'Selected Threads' dropdown select 'Disable notifications' then press OK. To enable notifications, simply do the same process, but select 'Enable notifications instead.
To turn off notifications for all watched threads, hover over your profile picture, and go to 'My watched threads'. Under 'Watched thread notification' tick the radio button next to 'Receive notifications for threads I've created'. If you change your mind, simply repeat the process and change to 'Receive notifications for threads I've created, replied to or I am watching' instead!
