OK, So before everyone tells me this has been answered before, I can't seem to find an answer that follows what I need.
I'm working with a real estate company, and they want to have WPMU so each of their realtors can have a login to the main site (to download files and other stuff) and so they get their own sites. That's all great, but the company wants to offer like 3 or 4 templates for the people to choose from. They ALSO want to offer the option for customization of those themes, or custom themes all together if the realtors want to pay.
To the best of my knowledge, themes are network activated for everyone. I've been told that on the MAIN network site, you can just upload a theme to the proper directory, don't network activate it, but activate it on the main site only. That's useful, but it still doesn't fix my issue.
Is there a plugin, or any way this can be done? I know for plugins I don't have to network activate them, but I can log in to the users dashboard as a network admin and enable specific plugins on that install only.
