Editing a persons details after inviting them

When you invite someone to your  Project.co  account you specify their email address, role and group. You don't specify any other personal information.
Then, when that user logs in to their account for the first time they can specify their name, password and add a profile photo.
It's not possible for you to edit a users personal information such as their name or photo because they may access multiple accounts on  Project.co .
However you can edit their role and groups.
To do this, navigate to the people page and find the user you want to edit. Then click the "Options" button on the users row and select "View Person".
From this page you can select "Edit User".
From here you can update the users role and groups.
