Wowza Media Server Configuration

I have installed wowza media server on a server which I can give access to remotely. I need wowza configured and setup so that I can stream two way live video via a USB webcam. I have already built the website and you are able to see yourself on the website using the webcam. You cannot broadcast however and the viewer cannot broadcast back. This is what needs to be done. There is not much work to be done here because the wowza media server is installed, so anyone with knowledge of this should be able to set it up very quickly. The website has been built and the video is showing so the integration is semi- complete. Wowza media server is somewhat like Flash Server 2.
