You have a new N icon at the top. I have to point out in advance that it is only for testing. It is not yet translated and functional at 100%. When you ask a question and someone answers it or adds a comment, N number lights up instead. After clicking, you can read the answer or comment. The same thing when you write an answer and someone adds a comment to that answer. He'll let you know too. Another feature is that it informs even if someone gives a thumbs up or down to your answer. Write questions and findings here. Thanks
