Forgive me if this is posted elsewhere. I've seen multiple questions put on hold because they are deemed too basic for this site who is intended for professionals. I think, as long as the question is a quantitative finance question and is posed properly, it should be allowed. What is the harm?
Take for example StackOverflow. It is most definitely a source for professionals, but basic questions are asked all the time and answered. Some even have very high upvotes.
