Sending RSS Feeds automatically from UNA to FB & Twitter and Vise-Versa

On D7, we have RSS feed URLs in most of the Mods which I use to send feeds automatically to Facebook or Twitter, but I don't see that on UNA. I am currently using {Posts} as an alternative for Blogs, and would like to send my Posts feeds to my Twitter page & FB. I was wondering if this is doable ?
Also, I was wondering if this can be done the other way - once a user post something on FB, his/her feed can be published on his UNA page..  Thx.
