We'll ignore the list of comments and comment submission form for now (don't worry, we'll get back to them once all other pieces are in place) and concentrate on the blog entry per se.
a. The blog entry itself, comprising of its title, content, categories, date and number of comments.
b. A list of comments and a form to submit comment.
c. A list of blog categories in the right sidebar.
d. A list of 'Latest News' (this seems to be the latest four blog entries)
e. Finally a list of archive periods containing blog entries.
