Best way to find roommates?

I was recently admitted into the Green Engineering scholars program so I will be in a quad room next year. Any tips on how to find compatible roommates? I worried because I have to find four roommates and am limited to just members of my scholars program. I have not been in contact with anyone in scholars as of yet, so any information about how to get connected with them would be great too!

Also, if anyone has any advice about living in a dorm with four people it would be much appreciated.
