Posting Questions for Students in Australia

Noel and I are in a group together to discuss Boy with the students in Australia. I have posted a couple of times, but the students have yet to log on and post. Many of the other groups have already begun posting, so I'm not sure why ours haven't responded yet. I am continuing to keep a check on it, though. I don't want to disappoint them. The teachers had asked us to lead the discussion, but I am hesitant to post any discussion questions yet, because I wanted to get acquainted first. The semester is beginning to wind down, so I'm really not sure if they are going to get around to it or not. I'm sure they have a lot going on, though. I know our students do!
