Private Messaging for Drupal 8

Hi. I am a complete Drupal newbie and am a bit lost. Hope you will be able to help / point me in the right direction….

I want to use Drupal 8 to ensure my projects have longevity, however I am finding that quite a few modules are not ported/reauthored for V8.

More specifically, I am interested in a module to enable members of my site to communicate with each other. PrivateMsg would have been great, but it is not in Drupal 8 and the author has indicated that he does not have time to do it either :(.

Do you have any module recommendations or is it something I can achieve simply by using the core features e.g. a message content type or even comment module?

Drupal version:
