Question regarding companions tab

Does the Companions tab let you message or reach your companions in an way? All I see is a non-clickable list that I can’t do anything with.

Is there a convenient way to reach or message your companions and stay in touch with them? Thanks.

There is no way to chat currently, you can pm the user if they are active in the forum.

Thanks. How do I PM? Is this the same thing as sending a message? (Complete with the topic and all that?)
