I am in the process of learning this website, I have seen in my discussion, that with every comment there is option :mark it best answer/comment" what does it mean and what is its benefit to that certain person. And one more thing there are star and inside star there is some numbering for every user, what does that stands for Please let me know Thanks

marking the best response means you find the best answer to your question or discussion. it benefits the person you are marking because there will be an increase on his/her rating.
