What I did was to seek out and meet or at least talk over the phone with people who were going to the same school as I was. Do not put pressure on people by telling them you're looking for a roommate, but simply tell them your current situation. Tell them where you're going to school, your major, your interests, the fact that you will be looking for a roommate at some point. The idea is that a better candidate for a roommate will come to that conclusion by themselves. Also note that there is no reason to push this because an ideal roommate will ideally come to that conclusion themselves that you should room together or at least consider it. I ended up with a person who ended up being a good friend and a great help and support during college. This is not the goal, however. The goal is to room with someone who will be conducive to your studies. That is, someone who would not be a negative influence or impede your college tenure. In other words, make your goals known, and let the selection of a roommate be "organic" -- i. e., relax.
