Here's an Ourboard board that demonstrates the key features of the service. https://www.ourboard.io/b/0b5a9bd8-93ae-446c-afbd-80ebfcb1e0...

It's read-only, but you can select all (Cmd-A), create a new board and paste the contents on a new board of yours on the Ourboard front page.

I now realize that a Fork Board feature might be useful.

Also having second thoughts on whether it's a good idea to have a "default board" that's read-write for anonymous users. Some political content observed on that one today.
