There are two ways to see the whole Hierarchy of your crew via the Rockstar social club, View your hierarchy and Manage your hierarchy.

To view the hierarchy of your crew:

1) Login to the Rockstar Social Club here

2) Click on the Crews link

3) Click on the crew's title that you want to view the hierarchy of (you can be in multiple crews, but only one can be active at a time). The text will turn a different color when you mouse over it.

4) Click on Hierarchy

5) View your awesome hierarchy!
