What is a "Roommate Coach"?

Okay, so you need a roommate. More than likely it's a financial decision: sharing 
expenses, especially housing, can make all the difference to a budget. And 
sometimes you just have no choice. If you are a college student and you want to 
live in one of the dorms, in many cases the only choice you have is to have a 
roommate or possibly more than one. So there are definitely times when the 
ability to make a roommate situation work well can be important if not essential.
