Although I often agree with @arc918 I’m not of the view that you should prod your admission rep “often”. I think it is important to tread that thin line between showing interest and just becoming a pain. It is good to contact the rep especially if you cannot visit. But I’d only contact the rep when you have a real question to ask, not just to say again and again that you really like the school or to ask questions that can easily be answered by looking at the school website. You want to come off as interested but not high maintenance.
