I have a Multisite Network. My main site will offer pro sites, for blogs. On it I am going to set up a classifieds ad site, a directory, and offer blogs.
Now when someone comes and registers a blog, and upgrades, I'd like to offer a package, and instead of each site charging, the classifieds for ads, and the directory for listings, and upgrade on the blog with pro sites.
How would you set a pro site level so they are given an "upgraded" user account, and automatically set up as users for the "other" sub-sites AND the main site?
I'm thinking they would just be set up independently of each other, and when someone joins the main site and upgrades, just manually set them up for the others or use coupons???
