after frosh year you could sell the fridge or use it for a wine cooler. (:
what we did was contact all of our suitemates/roommates via facebook and made a thread, so we could figure out what we're all bringing. If you're cool with everyone, the whole suite doesn't have to bring 8 microwaves and fridges, but rather share in the common room.
It also depends what college you're in, because of the layout of the dorms, and room size.
