Edufire.com

I just found this website, Edufire, and started thinking of using it.
http://edufire.com/
In this website, anybody can register as a tutor (or a student) and have classes (tutoring sessions with online conference software) of their favorite subjects. You set an hour rate for your tutoring session and do classes with one student or a group of people. Subjects, rate, time, and style of teaching are all up to you!
I suggest you go to the website and see what kind of class is offered now and how flexible it can be.

Web conference software?

I can't believe it's been more than a month since I posted something here last time...

I have a sort of random question.
What is a good free web conference software? and I feel like this is mentioned in one of today's tech talk. I some times use Skype but I need something else because Skype is only used for one-one web conversation, not for multiple people talk. I need this function because I have this group of Japanese conversation practice ,that I facilitate weekly in the semester and want to continue doing it even in summer when many people are out of town. I am thinking of maybe having one hour session per week where people can participate online using a software like skype except with no limitation of the number of people. What's the best way?

I guess I'll start looking right now...
