After the Errata and FAQ articles were removed from the GW website following the update, I sent GW (UK) an email asking what had happened to them. I got this response this morning:

"Hi Sam

Thanks for the email regarding the FAQs on the new website.

Currently the FaQ's are not available on the website, as the design team are taking this opportunity to fully update all the FAQ and Errata articles. This is only temporary and these FAQ's will be made available again in the very near future.

I hope that this helps, but if you need anything further, please feel free to contact us again.
Kind regards
Lydia"

So apparently we should be getting a full update for ALL FAQ and Errata articles soon, straight from the horse's mouth.
