More than 100 people have responded to a call in an online forum to take part in next Sunday's pro-democracy march. The website - Discuss.com.hk - claims to be politically neutral but one of its chat room threads posted early this month encourages people to march for universal suffrage. Dickson Cheung Hon-yin, who posted the thread, said the public had the responsibility to fight for full democracy in Hong Kong. 'We are now trying to contribute to constitutional development through the internet,' Mr Cheung said. More than 100 people have responded to his invitation to march as a group on December 4 since his message was posted on November 5. He said members of the forum had exchanged contacts in order to plan their participation in Sunday's march. 'We are a group of people that oppose dictatorship and support democracy. We share the same view,' he said. Mr Cheung said he would reach out to as many members as possible this week to take part in the rally. The forum has about 950,000 members. Web owner Francis Tong said the forum provided a platform for people to express different views. 'If they think they are not treated fairly, they should go to the march and voice their views,' he said. The group will gather at a fast-food restaurant near Tin Hau at 2pm on Sunday. Members will parade a large banner proclaiming, 'One man, one vote to elect the chief executive. Hong Kong's future is in our hands.' The march route is from Victoria Park to the Central Government Offices.
