In our constant search for roommates we've used lots of sites that rely on you to filter out scammers. RoomieMatch does this for you. There is a live person who reads every single profile for authenticity and will accept/deny your account. Yes you recieve hundreds of emails but THEY TELL YOU THIS over and over again before doing it. I found a roommate in 4 days and I won't ever use craigslist or anyone else again.
