There is a new series that I’ve written, about fun things that you can do with an announcements list in SharePoint.
Part 1: Create a Publish Date functionality for Announcements
Part 2: Create Alerts Based On Announcement Categories
Part 3: Modify the default “Current View” of the announcements Web Parts
Part 4: Create a “More” link to view the details of each announcement
Enjoy, and happy sharepointing!
