There is a new (at least new to me) company called Dimdim that offers a free web conference platform for up to 20 users.
I have previously been using GoToMeeting.com, but will be trying Dimdim moving forward. They also have Pro and Enterperise versions, but for the average small business, I can’t imagine you would often exceed the 20-user limit. From their website:
Dimdim Free. The world’s easiest web conference.
With Dimdim Free, people and organizations around the world can now meet freely. And since everyone will spend less time traveling and more time collaborating, this free product can actually help you make money. Take that, economy!
If you have any user-experience with Dimdim, please share your thoughts below.
