I tried searching for the answer but I don't really know if there is an official way to explain the question short of going into detail.
I have multisite setup for subdirectories at the tld. I am wondering if I can have like master-sites in subfolders that multisites are created under.
eg: site.com/ (wordpress multisite installed here)
site.com/fitness/ (a multisite blog controlled by me)
site.com/fitness/get-fit-with-mary/ (this is where a user created a multisite under the fitness site).
I hope that makes sense. The whole purpose of doing this is due to the nature of using completely different themes for the different sections of the main site.
There is no way to use more than one theme for a wordpress install that I know of, so using the multisite for all the first level sites would enable this. A last resort would be creating an enormous theme that is built to work based on categories of the top level site. But it seems like it would be easier to do this.
Any feedback on this would be great.
