The
wiziq.com that we've been using for our session is a free virtual
classroom and seams to be getting better all the time. They tell me
they'll be adding a feature to allow you demonstrate your desktop, a
webpage or software in the next couple days.
Elluminate is very good and easy to use. We used to use it via a
license with an organization we were part of had. We don't have access
to it anymore, however. The vroom works well for very small groups.
Here are a couple other tools that offer free web conferencing - I've
not tried them.

If I find a few free minutes, I'll check outOpen A circle.
Also, Skype
http://www.skype.com - has some features to do web
conferencing.
You may also explore
meebo.com - you can set-up your own meebo chat
room and you can embed this chat room on a website or in a course
management site.
Remember that web conferencing is different from just providing a
narrated PowerPoint or presentation. Web conferencing is only for
those environments where you want to gather everybody in a virtual
space at one time and you want to converse with them live via
microphone, text and maybe a web cam. Also with these tools you have
the ability to share a presentation, whiteboard, and other media.
Another point to remember is that often times when you buy the web
conferencing software you also have to pay for streaming server space
to host the web conference or you have to have the ability to put the
software on your own server.
> I teach at Harper College and we have a license for Elluminate Live,
http://www.elluminate.com. It's a bit pricey but the entire college
> shares about 30 seats. I use it for online orientation sessions and at
> intervals throughout the course for topics that students sometimes
> have trouble with. The sessions can be recorded. Another teacher at
> Harper uses Elluminate Live while she teaches the classroom section of
> a course -- the online students can remotely participate at the same
> time. All students can review the recorded session later.
