To check your genealogy you have to login to your Back-office, go to section Genealogy->Binary Team Viewer OR go to the bottom of your Dashboard itself and you will find there: Binary Team Viewer.
This is also where you can define your default placement of new users in the tree. Left, Right or Auto. Auto means, that placement will be selected automatically.
To browse down your tree, click the "Next Level" or "Bottom" link under the Selected User in the bottom of your tree.
This will allow you to drill down in your genealogy tree.
