Perhaps I’m missing something. This sounds pretty much like ordinary MODx content pages. How is it different than normal pages? You want them listed by date? Who "posts" the article? Are they site admins, content managers, general public (oh my!)?

I could be totally wrong.
If I understand correctly the easy way would be the blog solution which you get when you install the test website during installation...and remove the {{comments}} chunk from at the bottom?
