How do a remove a person from a contact group? I have a person who joined our chorus. He is in a contact group for nonmembers and gets emails intended for them. I can unsubscribe him from emails of type "contact", but I can't remove the contact. I don't want to keep it as we now have his information with members. I've looked at admin permissions and don't see anything else to add. Do I need a feature request or am I missing something?
