News box on homepage

[Floppy]

At the moment, the home page is very clean. Which is good. But it does mean we are a little bit limited in using this first page to communicate extra stuff to people. Could we think about a news box or similar on the home page, we can then use this to publicise a sponsorship event that might be happening that week, or give the amazon stuff prominence, or link to whatever we want to publicise that week - we can change the info in there frequently.
