I am the leader of our co-op. We have had quite few requests from players to join us. The problem is that when I try to accept them I find out that they need to leave their own co-op first. As an experiment I have tried to join another co-op but get told the same thing ie that I have to leave my co-op first. How is it then that some people manage to get around this? Some appear to be very good players who would be a real asset. How can I contact these players to tell them to either accept them or tell them to leave their co-op?
