That would also be a great idea, but it would be really cool to have the chatroom open 24/7, that way, even if after a lesson chat was scheduled, you might be lucky and find somebody on the chat room that is also looking for information on arranging.
I don't know if it's wise to start a chatroom for this course because
* What do we think about the time differences between all the different countries?
* Can everybody read everything at any time or will it be deleted after a while?
* I also like the professors comment and will that be stored so everyone can read it?
* This forum is almost a chat room so for me it's ok the way it works already.
