I'm looking for the silliest, most obvious (with hindsight), most basic questions possible about DJing. Things that you struggled to work out (or are struggling to work out). No question too basic, no question too silly. It's to help with an absolute, absolute beginner's guide. Think back to when you were considering digital DJing or had just started (maybe you are one of these things right now) - what do you most want to know that you' can't find the answer to?
