I went today around, now you can add a small biography to your profile and link facebook, twitter, IG or Tumblr (yeah, only those).
There's notifications for subscriptions now, I checked one I had, it was an "I'm done, come with me to CF" update.
I'm curious if there's notifications for comments too, I haven't got any these last days so I don't know.
Still no way to communicate directly, indeed.
