Guild Wars 2

The hardcover guide I bought says the code inside can be used to access the digital guide where do I enter the code?

i’d like to know this aswell

what is the site

It’s likely from whoever made the guide.

I’ll just point out to those that haven’t bought the game that they should not buy it. From what I have seen in the guide, it’s worthless and very outdated. Look to these forums, the wiki, and other free sites for information.
