You can see and manage your own hubs from your profile page. If you're in a hub, the profile page can be accessed from the in-hub phone menu.

To create a new hub, use the "Create" button at the bottom of the screen

You have a maximum of 10 hubs you can own.
To edit a hub, select the hub you would like to edit. This opens its hub information window. Select the "Edit" button. This is also where you may change your hub status from private to public and vice versa.
Please note that home hubs are always private.
To go online with your home hub, simply select the invite button in your main display.
To go offline with your home hub, go to your home hubs information window, and select close.
