Some blogging systems allow the blog owner to install third party plug ins that add additional functionality to the blog. For example: MovableType, a powerful blogging solution, allows the owner to install plugins such as Workflow. The Workflow plugin allows the blog owner to have editors on the blog. Students can be editors. When they "publish" the post goes to the author, the teacher, for approval. If the teacher approves the post it is then published to the blog. Plugins are an advanced feature that most beginning bloggers will not yet need to use.
