I am trying to set a specific client to to be able to join a specific channel without having its password and without giving them server admin privileges. However when I go into the client channel permissions to b_channel_join_ignore_password it only allows me to add grant permissions, the add permissions is grayed out. I am assuming that is the one I need? If so what do I need to do to enable it? If not which one do I need to get it to do what I want?
