It's the "Featured" channel, not default. Sorry... I was posting without having the BB8 in front of me.
I am doing this from the BB8's UI, should that not be hte most robust way (from the device)?
all my devices show up on both domains [http://insignia.chumby.com/mychumby and http://www.chumby.com/mychumby ]
naively assumed they are the same or interchangeable; I assume not?
EDIT: Via the Chumby site, I renamed both "featured" channels. I appended the name with a "1" for the first and a "2" for the second and then via the BB8's UI, I deleted "featured1" and now all I see is "featured2".
Perhaps the backend is smart and since there were two channels with the same name it would not delete either of them?
I first tried to delete one via insignia.chumby with no joy, then chumby's version with no joy and then checked my Chumby branded devices and there were two channels labeled "featured" (which I assume has always been there since I setup the BB8, I just never checked and it was obvious on the BB8 by the nature that it works and you select channels) too. Then I renamed them via Chumby's version of the site and voila...
So that is taken care of now, thanks for the help, I don't know if I would have tried that if you didn't get me tinkering....
