I found a Theme I like that has the registration right on the top/front of the home page. (see screenshot) My idea is to get people to sign up for a free website and then then can upgrade later to a premium version.
1 - Would it be possible to use a form like the one in the screenshot to create a Multisite immediately after they sign up? Would I still use Pro Sites for this? How would that work?
2 - How would the process work after they have their free site at http://TheirName.MYSITE.com and be able to upgrade to premium features?
