Classes in Virtual Class Room can be fairly high bandwidth. You must use a wired internet connection rather than a wireless connection.
To run Virtual Class Room, you will need an up-to-date browser (like Firefox 3, Safari 4, or IE 7/8), as well as a compliant version of Flash. The first time you log in, Virtual Class Room will ask to install an add-in, which is required for optimal performance.

All users must listen to class sessions using headphones, not computer speakers, to avoid feedback when their microphones are enabled. If you have a built-in microphone that you prefer to use (such as those on many newer Macs), you must use basic headphones or earbuds in conjunction with the built-in microphone, or else there will be feedback problems with the audio. Please make sure that you have your headset in time for the first class session.
