The site may experience some brief downtime sometime during the next few days, as we move Challenge Accepted to a new web hosting provider. We’re really excited about the move! Our new hosting will, among other awesome qualities, allow us to have far greater control over the site’s resources, which will lead to a much better experience for you guys!
We will make an announcement as soon as we know exactly when the (brief) downtime will occur. Watch this space, or our twitter, for updates.
