I have 2 sites set up in a multisite environment. Mainsite.com and Subsite.com.
I would like a new user registration in Subsite.com to also apply automatically on Mainsite.com.
I also need to create a new post (CPT of Job) while still in Subsite.com but the post needs to be created on Mainsite.com. This will follow successful registration as above.
So my questions are simply how to get both the user registration and the post creation to occur on Mainsite.com when the forms are on Subsite.com.
