I saw a few topics mentioning that you can add new sites with the User Registration add-on, but I have no idea how to set this up.
I've added a form, used that form for a new User Registration feed, but I don't see an option to add a new site. It's on the mainsite btw (read that there's a restriction for it on sub-sites).
Should I be getting an extra option for the feed or how does this work?
