I am doing a demo of setting up a Kanban board using Trello. I can create boards, and associate them with a team (or vice versa). But... I can't seem to add members to my teams. The teams are fictitious as would be the members. Therefore the members have NO valid email addresses to use. How can I ADD members to a team without using an email address (...no invites need be sent...this is all for demo purposes).
