'The power that can be unleashed by the internet is overwhelming. Whether the power is positive or destructive depends on how users harness the tool. That's why it's of the utmost importance to teach the young proper internet manners and ethics,' said Cheung Chi-hung, principal of Yaumati Catholic Primary School.

Christopher Yu, member of the Joint Council of Parent-Teacher Association, said the concept of sharing files over the Net presented many problems. He said there's an unspoken agreement among Web users that everything on the Web is for sharing.

'Given the wide-open nature of the Net, users have to bear in mind that things said on the Web can never be taken back.'

Teresa Cheung, senior social worker with Hong Kong Family Welfare Society, said the Net had created a gap between children and their parents.

'Without a firm grasp of the workings of the Web, many parents complain about their children's indulgence in the internet and worry about online risks like virtual harassment and dissemination of unhealthy information,' she said

New technology is often fraught with risks. The key is to better harness the tool with a positive mindset.

Vice-chairman of the Internet Society Hong Kong, Edmon Chung, spelled out a list of measures, such as installing filters, which can ensure cleaner cyberspace. In addition, students need to be taught proper Web ethics.

'Respect is the key. Only through respecting yourself and others on the Web can we reap the positive benefits

of the internet to the full,' he said.
