Class Blogmeister

Class Blogmeister, from the Landmark Project, is designed especially for schools, students and teachers.
“
There are many freely available tools that facilitate blogging, but
none seem especially suited for the classroom. That is the reason for
BlogMeister. This online blogging tool is explicitly designed with
teachers and students in mind, where the teacher can evaluate, comment
on, and finally publish students’ blog articles in a controlled
environment.”
