Well, MIT doesn't recruit per se (which is to say: not like a division I school), but there's a form you can fill out on the athletics site if you're interested in playing,
here. If you're interested in playing in college, you may as well fill out the form.
All of the varsity athletic teams have tryouts, but I'm not sure how they deal with informing students about them -- fall athletes arrive early for orientation so they can begin tryouts.
