I Have Begun to Create a Blog for a Classroom

I have been keeping up with my edublogs blog and that is one about my reflections as I am learning through my Library Media Specialist program and Minnesota State University-Mankato. I am trying to create this blog as one for a classroom setting. I am not sure how to get learners as authors on this site, but it seems they nee to have an email address. In our district they do not so I may use the people in my class unless I can figure out a way to allow learners in my room to be authors. I created a blidget of my blog but can not figure hot how to get it on this site. It acts a bit like an RSS feed. That may be easier in the long run. I pasted the blidget url in this post and it came up. And I just went back to Widgetbox and ws able to add it as a widget when I clicked the blogger button.
