Week 6, Thing 14 Voice Thread: Adding to Your PLN

Spent the last 90 minutes playing around in Voice Thread and stumbled upon this one about PLNs. I was kinda excited so I joined it. Voice Thread seems like a great learning too, but I am trying to figure out how to use it with classes - especially at the high school level. Do you just have all your students join on their own? Most of the kids at our school have their own email address, although I know of a few that don't. I can't see them operating out of a teacher's account. If you are using Voice Threads at the high school level - fill me in!
