Virtual Class Room is one of the options for live web conferences in eKnowledgehub.This documentation refers to "classes" and "instructors", but Virtual Class Room can be used for one-time seminars,guest speakers, and other special events as well. If you would like to discuss the possibilities for using Virtual Class Room for your course or event in eKnowledgehub, please contact our support at support@eKnowledgehub.com.
Most classes require students and faculty to participate in Virtual Class Room sessions using microphones for voice chat. To communicate in live sessions, you must have a compatible microphone and headset, as detailed below -- your computer's speakers will not work.
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.

For detailed hardware and software requirements, please see Virtual Class Room - System Requirements (note that there are different requirements for web conference participants, presenters and hosts).
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.
