I am a site owner for a military unit (we are going heavily to SharePoint.) We have SharePoint 2007 installed, and have no flexibility to add more web parts. We also have limited ability to customize site properties.

I would like to create a function for the boss (my commander) to display a weekly update to his unit. He is not highly technically proficient, so I'd like to create a form or maybe a simple rich text file that he can update, then for those words to display on the site's home page. This will need to be updated every week.

Any suggestions for out-of-the-box web parts that I can use to make this a reality?
