Frosty Fog

I joined Joe Tree's questions and answers session yesterday evening but didn't phrase my question correctly.  Those of us who referred to a merger were told in no uncertain terms that it was a partnership, but of course there is no edit feature these days so none of us could quickly edit our question or add to it.

I asked  As part of the merger who decided that the White background would be implemented?
Answer:  It's not a merger, and the new design was entirely conceived and developed by the Blipfoto team.

What I failed to add was whether it could or would be changed back to grey. 

The trees say it all.
