[Schools that notify you when app is complete / Schools that don't]

A few schools I applied to request DVD/CD portfolio instead of online portfolio, and I noticed that some of them do not really contact me regarding whether they have actually received everything in my application or not (e.g. Cornell). I don't know if anyone else also worries about the same thing. Also, has anyone checked their application status for columbia? I submitted my application in december but it still says "incomplete" because "slide room portfolio: not received". I called and emailed, wanting to ask if that's a tech problem or if they just haven't gone through updating everyone's app status yet, but no one answered. Any idea?

just to let you know Cornell did send me an email letting me know what they haven't received yet.
