Clicking on "Add New" in the content area of "Networks" gives an error message about not being able to load. Clicking "Add New" in the sidebar brings up settings for creating a network. But, it either ignores or refuses to add anything I provide without any kind of message. It just blanks out all of my settings.
I understand there are known problems since WordPress 3.5 and that fixes are in development. Until that time comes, the WordPress compatibility needs to be rolled back to whatever version it does work with.
I also understand that there is a "trunk" version (whatever that is) that can be used as a beta with WordPress 3.5 and up. If that is true, it should be offered in a more formal way and explicitly as a "beta" version.
And, please delegate someone who can figure out how to use this plugin to write some instructions for it. It's very frustrating to figure out without even a sliver of an example available, even if it did work.
