Demo site is up - but don't tell anyone!

The demo section of this site (running as a sub-separate site, actually) is now up and running: but don't tell anyone it's there just yet! The 'demo' page doesn't yet link to it. This is because the demo section isn't quite ready yet.

If you have a look at the demo site, you'll see that you can already play around with it (using the same login, and even the same session, as you do for this site). But the whole "this site resets every two hours" business isn't exactly happening at the moment. I need to write a little module that implements this database reset in a cron hook. Once that's done, the demo will be ready for public consumption. Won't be long!
