I'm sure this has been asked before, but I can't find a thread discussing it:
I often use the "Show new replies to your posts" link to check for updates in threads I have been recently involved in. But sometimes a thread drags on and on, maybe moves in a direction I am less interested in, and I would prefer not to track it any longer. Is there a way to "unsubscribe" from such a thread, so that it no longer shows up in the "Show new replies to your posts" list?
