Werewolf for Confluence is an app that allows switching into any user from any place in Confluence.
Sometimes you need to see how other user's system looks like or how it works. With the Werewolf you can turn into any user in one click. And then you can see the world through his eyes without knowing his password. The right to become a werewolf at any time can be given to different groups of users.
