Blogs require you to login to a user space - username, password - at the begining of your blog setup.

The author of the blog can choose differing templates or the "look" of the blog. Access to a control panel allows the blog owner to make changes to how the blog can be accessed, who can reply to posts or many differing security settings to ensure spam is avoided.

A range of editing options are provided for each and every post or blog entry.

Readers can respond to the the blog authors posts by using the 'add comment ' feature which is generally in a discussion thread format.

This process becomes evident when you begin blogging. The hardest part as an educator is understanding what is relevant for comment or inclusion however, how a blog works is generally straight forward and understandable - in other words - intuitive.
