Hi there,

Your friend can share an Ideabook with you so you don't need to log in with her details. She'll need to select the Ideabook she wants to share and click 'Collaborate' (top left corner). A pop-up window will appear, where she'll be able to give you access.

You can view the Ideabook when you log in to your account and click the 'Your Ideabooks' section.

Hope this helps!
