So...would be cool if it worked...
Sub folder multisite set up nginx
Right now if you create a site, edit it make it awesome. And then add mapped domain...all links STILL refer to the subfolder link and aren't updated...so after you map the domain you have to go in and RE-DO all the links. Re-doing all the links uses the new mapped domain...but would be better to have a feature that can auto update all the old links....computers!
A bit of an oversight...but important for this theme to be working.
