If the site is looking odd (i.e. you can see lots of orange and bits of the old site) that is because your browser hasn't got over the shock of how good the new site looks.
To fix this, refresh the page a few times, do a hard refresh (CTRL+F5), or clear your cache from your settings.
Clearing your cache may log you out, so be prepared to log back in again :)
It might seem a little bumpy at first, but we'll get there!
