I don’t want the credentials to be only for the subsite, I want the user to only see the subsite when he’s registering. I do want the credentials to apply for the whole multisite which is what I thought your plugin did.
For example, if someone is registering for whitehorsemissions.com, I want them to stay on a whitehorsemissions.com registration page, but have their credentials stored normally, so they could login to wp.resilientword.com as well. I thought your plugin would enable this type of behavior.
It doesn’t really sound like your plugin description matches what you say it does. The whole point was for the subsite to be the registration. I’m not sure how your plugin is a solution to anything.
