Don't know where to look for answer
In the last two weeks I've been trying to clean up a lot of my PMs and other subscribed threads in settings. But one button I don't use and don't know what it does is the last of three actions you can take at the bottom of a thread. First is "reply", second is "reply with quote", third don't know what it does. Also can someone explain how they "bookmark" without going thru and subscribing to everything they comment on.
