Where are my students?

I thought I would have seen some commenting in Plastic Plate by now, but so far, none since class last week. I have suggested that they should/could in an email, and I have put more info for their current project, (suggestions, clarifications) on the blog. How do I know if they are using it? How do I get them to start taking it over?? I guess I’ll just post that question there and see who answers.
In class tomorrow I am going to show them more about different kinds of blogs and get them prepared to make their own research blog. I have to have them use the template I have going, or else choose one which already has a button for rss feed in place. I had better work on that some tonight, come to think of it… They have to set them up properly so I can do an rss feed thing to save my own sanity when I am trying to keep up with 18 blogs, plus these two!
