Thanks for your responses on this. I sent a message to the blogger, striving for a tone that was neither threatening nor indifferent, and conveying my hopes that we can find a resolution that works for both of us. Haven't heard back yet, and now I'm away for the next 3 weeks. Will post any interesting developments on my return if anything transpires while I'm away.
