This contribution is sort of a news blog. You can make new articles from the admin section of Oscommerce. Users can add comments to your articles. You have complete editing control in the admin section.
Every article is sorted by date in the store and the admin section. I used the mysql SELECT DISTINCT function to sort the dates. It has a static automatic RSS feed function. When you write a new article all you have to do click "Create RSS" and your done. Users will always be up to date. See the preview pics in the preview folder.
