The link to the ticket x-change was specifically provided in that IMP update. One would hope people aren’t abusing it...
As of now, all shows are going on as planned and attendance has not been affected. Naturally, if a show is canceled, refunds will be provided. If someone is unable to attend a show for any reason, we provide a forum for patrons to buy and sell tickets at no additional charge through I.M.P. Ticket X-Change.
