Subscribing and un-subscribing to a thread

Click on the "User CP" button in your page heading. Under "New Subscribed Threads" go to the thread you no longer want to subscribe to and click the "unsubscribe" box. That will clear the subscription.

Another way to do this, is to open the thread you no longer wish to subscribe to. Above the first post are four buttons. Click on the "Thread Tools" button, then click "Unsubscribe from this Thread."

EDIT: Posted at same time BHW was posting.

 

You can also manage your individual subscriptions by clicking 'List Subscriptions' under 'Subscribed Threads' in your User CP. Here you can select which subscriptions you wish to manage and delete them, move them to another folder, or change their subscription type.
