1. How can I quickly see all the threads I participated in that got new replies since my last visit? I guess the closest thing is "Favorite Topics" under "My Home" link, but then you have to remember to mark each thread you respond to as your favorite. I don't see an option to mark them automatically/by default. And also, even if there was no new replies, they would still show in "Favorite Topics" so that's not really what I'm looking for. 2. On other forums, if there was an activity in a given thread since your last visit, you would know that because the subject of that thead would be displayed in bold. How do we determine this here?
