I'm not sure what the server side language is. The site is built on a template platform and I don't have access to the service side. I can, however make changes to the templates. I would prefer a message that appears on top of what ever the landing page happens to be. Thanks!
My idea is to place a <div> at the top of each page (or anywhere after the header, if you have one). You can add the <div> to your template but I think you will still need to edit each existing page to add the <div>. Then you need to create an announcement page (a page that contains only your message, you could wrap the message in <p>...</p> tags). Then you use a server-side script, like PHP, to test if the file exists - if it doesn't then you hide the <div> - if it does then you use PHP to insert the file into the <div>. You would use CSS to color the <div> in colors that stand out.
For this to work you need some kind of server-side language. Check with your host provider to find out what server-side languages are supported. You would also need to upload your updated files to your server, which you should be able to do now.
