Incorporate news letter into existing site

I have an existing web site that I want to incorporate a newsletter into. The site does not need to send out the newsletter, which will be done by a third party, but to simply host the stories. Under the "News" Tab on the menu bar the page needs to list the newsletters i.e. 1. May 2009 News Letter 2. June 2009 News Letter If you click on the May 2009 News Letter, for instance, you would be linked to a page titled May 2009 Newsletter. Under the title would the title of each story in the Newsletter with the first four lines of the story. i.e. 1. New ID Cards Issued. Today the government announced that they would introducing new ID for all citizens living in HK. The foreign minister announed ......more If you click on "more" you would be linked to the page with the full story. The process should be simply managed from the admin section. Ideal way would to create a template which would include: 1. News letter title (this would be May 2009 News Letter) 2. Story one a) title b) contents c) picture Story two a) title b) contents c) picture The system should allow for an unlimited number of stories to be uploaded. Once uploaded the system would create the necessary pages on the website.
