My classmates friends want me to post their questions as well.Thats why there are multiple names is there a problem.
Yes. You are posting duplicate or even triplicate questions. That is silly. If we have answered one, the answers to the others follow. People here are volunteers, they are not likely to want to answer the same question several times. If you irritate volunteers, they stop volunteering.
To add to what Bob Pursley said, it is also confusing. Tutors must go back to the original post from time to time in order to determine if there are follow up questions to the post and/or to the answer we gave. Sometimes we use the name and sometimes we use the post subject. It is laudable that you are helping your classmates; however, it would be better if they posted their own questions.
