I've just finished teaching an undergraduate literature class which ran for the last few months. Every week, my students would meet up outside of class and discuss the text they were reading, and prepare a short report. These reports were all posted to a Facebook group.
I'm now going to the Facebook group and copying all of the reports into an email so that the students have them all in one place as they prepare for their exams. However, it seems that the group has only kept posts back to a certain date.
Maybe I'm misremembering when we started using the group? Or does Facebook actually archive old group posts? Is there a way I can access these older posts if they exist?
