I'm not sure where to report this, or if Ning will respond to these kinds of issues, but so many of the apps just don't work, and this Nutshell Digest app is one of them. It used to work, and now it doesn't. So many of the apps are either broken, or unsupported, or do not mesh well with the sites....
Anyone have a solution to the Nutshell problem? The app loads, but does not allow "save" so that someone can sign up. It just hangs there.
