None at all. It's a pretty straightforward feature. Instead of going through the process of "going online", you just select the quick race, and it will connect to the server and drop you in a lobby. It shows you the race setup (type of race, environment variables, etc) and lets you see the profiles of the other racers.
Pretty good.
