I'm using the user registration add-on on a multi site install to allow new users the ability to create a site when they register.
I've just realised that the multi-site option that you usually see from within the User Registration Settings is only visible if you create a new form from the main network site and not another site that I have created. Why is this? Ideally I would like the user signup form on site B rather than from site A which is unrelated.
