It is not often that I use the google hangout feature as sadly but honestly i do not have many friends. However, with Chrome having the notification and hangouts addon and Google Plus having hangouts on the right and Gmail with hangouts on the left. I see the list more and more. and What i am noticing is i have no idea who the people on that list are. and in one case there is someone on there that is not even a person it is a support page for a service i once used.
Is there any way of removing unwanted people from the hangout list? i have looked around and have been unable to find any articles on this matter.
