Registration Form: 'How Did You Hear' Needs To Be Required

It is imperative that we know how our families found us to create a better marketing plan and increase registrations. DSP needs to give us the ability to require the "How did you hear about us?" field AND to make it a drop down with options where we insert the various methods in which they heard about us. As we all know, parents will not complete that field unless required and therefore, we are missing vital marketing information.
