Most of us know that you have options in your settings to notify you if someone replies to a thread you've created in forums. What if you like a thread created by another user and would personally would like to know if people are replying to it. My idea is sort of based on the old version of "saved threads." When you "save" a thread you can set options to notify you when users reply to it even though you did not create it. I wish they would bring back the save thread functionality. What do you think of this idea?
