Of the 20 groups listed here on my Ning site only 13 made it through the import ... i.e., are visible on Groups page. Looking in the datastore browser they rest are simply not there.
But all 20 are in the JSON files as can be seen in the screenshot.
The view JSON archive tool in PHP array is very cool.
One note, Paul, you might want to consider making the default selection null (i.e., "Select an archive") because the first archive (blog) could be huge and take a really, really, really long time to load.
