The template of this page is "announcements".  Each week, you'd have to make a "new post" and attach the bulletin to that page, along with anything you wanted to say or show about that week. In THIS section would be the generic welcome info that's at the top of the page.

Regarding the slide show, I'm sure there's a way to make the black bars go away, but I don't have time to tinker with it. It wasn't difficult to create, though a little time consuming for the first one. Once we figure out how to configure it correctly, I think it would be pretty easy.
