Just came across a blog entry on the integration and use of WiZiQ in moodle. This is a tool to have free online classes:
The online Virtual Classroom on WiZiQ is a free alternative to expensive conferencing tools selling as online teaching/learning software. Distinctively, the prime focus of WiZiQ has been to create a user friendly online teaching and learning platform for the educational community. A minimal but useful feature set always works better to keep things simple. Thus our virtual classroom requires no download or installation and integrates perfectly in Moodle.
