It looks like you've already using the help page which Penguin-Pal linked you to on your main page, so it would be easiest if you just edited the "I am a box containing content in the left column." box with your message, no need for any voodoo.

It is technically possible to just the message in a single template, and use the template on the main page, and load the template into the right column - but there is a bit of voodoo to do that, and the template would have to be retrieved on every page view, so it would be better, and faster, to just write out your message on the javascript page. You could still put the message for the main page in a template, but since the template would only be used the once, I would personally just put the message in the main page itself.

edit: I just realised that your left column was in the right column, so it looks like you might still have a little work to do there. ;)
