Many TAC staff presented in seminars and chaired sessions, most prominently TAC Secretary Sipho Mthathi and Treasurer Mark Heywood. Heywood was a panelist in a plenary session co-chaired by CNN's Sanjay Gupta entitled "Time to Deliver: The Price of Inaction". Towards the end of the session, supporters of TAC, many of whom were wearing the distinctive "HIV POSITIVE" T-shirts, took to the stage behind the panel and silently held placards containing messages such as "Fire Manto", in reference to the Health Minister, who was in attendance.[11]
