I've added someone to an existing private conversation by accident! How do I delete the conversation and ensure that the person I added by mistake can't see the past posts? How do I make sure they are off there if I continue the conversation with the intended person? Thanks
Yes, delete the entire chat is the way to go. You should also try to set up a BBM Group with the people that you want on that chat. This way, you'll be safe from inadvertently including someone else since it takes a few steps to add people into your group. Make yourself the admin of that group as well.
