Does Mathematica StackExchange have a way to follow questions. Some times when I look at questions I come across good ideas that I could use for later. However, when I need to refer to them, I can't seem to find the exact question and answer. It would be great if one could mark questions and answers.
Another thing is when there is a question posted that hasn't been answered yet, but I would like to know when it gets answered, is it possible to mark it so that you would get a notification as soon as answers are provided? I am obviously talking about other peoples questions here.
