That is all done now.
Sure is and I've subscribed.
Do I need to do anything else to set up the RSS feed for Followers?
Your email followers must subscribe anew as there's nothing you can do except write a blog post pointing to the new feature.
I suggest you open a

Remember Google is your friend when trying new things.
