I see that every Nabble forum has an own domain given to it by Nabble. I would like to create a forum to embed it into my website, but I wouldn't like users to be able to find it in Google separately with that Nabble domain. Is there a way to set the robot.txt file for the forum to disallow its indexing by search engines?
