Yes, different from Forum registration (you can register in the forums without owning an eDGe). You register your eDGe on your eDGe by pressing "Menu" - Settings - Edge Settings - Register. Once registered, you run the "Store" app and click the "My Account" link, where you'll see the Ermine update message text in red (you can also log into the www.entourageedge.com website and click My Account). Once you've "opted-in" on the beta, you run the "Update" app on your eDGe to download and install the Ermine beta.
