I looked again at the admin panel, there isn't a means of changing that banner link. It is a home page link within the forums by design I guess.
I was looking at some new color palette options for the boards as a whole, maybe turn the thing black and green to match the .org site. Unfortunate part was the 'preview' function didn't work, so I had no way of knowing what I'd unleash if I 'installed' a new scheme. I let sleeping dogs sleep and be dogs on that one.
