Anyone know a way to have WordpressMU to work like this:
New user registers an account and thus is registered for the whole network (default functionality in WP Multisite), but then he/she would be required to "ask" for an access for the sites within the network one by one. The network home page would be accessible for everyone, but the subsites should be private.
So in essence, the user has one username and password for the whole network, but in order to view the site, the user has to be given rights to do so site by site basis by the admin of the site.
Any ideas? Plugins? Anything?
