Have you seen Elluminate yet? WOW! Good stuff! Expensive, but good! They offer a free "vRoom" that allows up to 3 simultaneous users to have a free online conference or "webinar."
Since one of my goals this year is to get PD 2.0 up and running around these parts, I'm asking for volunteers (aka guinea pigs) to test out my very own Elluminate vRoom.
If you're interested, please leave a comment or email me at dornberg at misd dot com. We'll set up a time and I'll send you a link to my vRoom.
