Sharepoint 2007 Important message web part

Hi
is there a web part that will work in the following way on sharepoint 2007:
 
I would like to place a "hidden" webpart on the home page of our site that will only display content if a certain list is populated. We want it to point to a sharepoint list and when a user inputs an important message the webpart will appear on the home page with the content of the message. such as

Important:

- Due to important maintenance .....

etc

Anybody know of such a beast?

Regards
gary

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can use an Announcements web part, but the difficulty is to hide the defaults that show when there are no entries in the list.  If you have SharePoint Designer, you can use conditional formatting to hide the Title and Body columns when the column is blank or contains the default text.  Then set the web part to have no Chrome. We use this to show alerts when we expect server downtime, etc.
