This evening, one of my almost students in Blogging English emailed me privately with a question about starting a PLN. I replied but directly to the blog (sorry the blog is private - just for the class). Then I found the student had not yet joined the class, so I did have to write the student privately to explain that he was not a member of the class until he joined the blog. I can't imagine why he thought he could be part of the class without joining it. That's a new one - and something to address in future letters to new students.
Now I need to find a few "PLN for newbies" links and decide how to organize hosting student PLNs on the blog. I can add pages, but we don't have an unlimited number available. I think each student can put PLN in a post and then edit as needed.
