It's really up to luddite (or whoever ends up hosting it this year) to decide what they want to do for a website. I have, however, started throwing a few ideas around as far as design goes. Here's what I've come up with so far:

The text is just a placeholder, I copied it from the page I made up for last years challenge. Again, of course, it's up to the host to decide on the design they want to use.
I guess it'd be a good idea to have a final page in place by Christmas time at the latest, so we can start promoting next years 'challenge fairly early.
As for hosting and bandwidth, neither are a problem.
