Hi ACHTUNG MINEN,

Do I understand you correctly, would you like to send a private message to a member?

To send a private message to someone in the lobby (or when you are watching someones game) , click on their nickname. 
   /msg "nickname"    will be shown in the chat box. You'll have to click the player's nick for every new private message you want to send him.

It's different in the new bowling game.   

https://www.flyordie.com/bowling/

  
There, you click on the player's nickname. A menu is displayed. To exchange private messages with this player, click on "message" 
If you want to delete the private message/s later, click the 3 dots and "delete conversation"

I hope that this was, what you were asking for.

Kind regards

Edit: I think i know what you really meant: you don't want to click the member again in order to reply. That would be great. I'd like that too. 

have a nice day and good games!
