I need to be able to allow users to leave comments on author profile pages.
I came across another answer here that has given me a basic outline of what needs to be done to allow it:
That said, I am unsure how to proceed with getting it implemented. I have created a custom post type to hold the comments, but I do not know how to make it so that each time a user/author signs up to our site (we are building a site with open registration), a post gets created in the custom post type to hold comments, and then automatically associated to their user profile.
Would much appreciate a more detailed answer than what was provided on the linked question, so that I am able to understand exactly how to get this up and running.
