Did I stumble on Showcase with thumbnails somewhere? Clicking on Forums-Showcase and tags Showcase give me posts. Strange- I'll have to backtrack and see what I did.
OK, I somehow got to themehybrid.com/showcase/ which displays Showcase with thumbs.
I am likely missing the obvious, but I don't see a clickable link for the Showcase thumbnails page. (Again, I'm probably just missing something.)
