A blog is a few paragraphs that someone writes for public view on the internet. It may be very very short, or alternatively, ramble on to great length. Blog sites usually consist of 1 author (the person who owns the site and posts blogs) and many followers who may comment about each blog.
Our site is likely to be a little different in that we have a CMS (content management system) which in theory is more organized. What I have labeled “News” is where we can blog and all persons who have the designated “role” of author, editor, or administrator can post a blog. Their blog is added to the top of the list and all others are pushed down. In all ways, this could become the Courseboard !! That may or not be desirable, something we need to consider.
Changing the front page is either 1) as easy as posting a blog – as in exactly, or 2) Nearly as easy. The way I envision it, we would have the role “Editor” for any member that can change the front page.
