We received a question today that might be helpful for others:
Q: "Can I allow students rostered into ONE of my haiku classes to communicate through haiku with students rostered in another haiku class? I am a secondary teacher and I'd like for some of my studnets to be able to dialogue with students in my class who see me at different periods?"
A: That's an excellent question...and the answer is 'not really' and 'yes'. :)
There is currently no way to have students use the Inbox or Discussion features to communicate between classes...each class is a domain unto itself.
You could create a "unified" class for discussions only, and import the rosters from the other classes into that class..not ideal...but it is a workaround.
You have another option if your school allows you access to Meebo Rooms. If you create a chatroom in Meebo Rooms and then use "Embed the Web" to paste the same code in two different classes, students would be able to chat with each other across classes securely.
