OK, so Mr Williams hasn't responded (can't say I blame him).

When someone says that a certain site is 'safe' I see that as a challange cos I know its not true.

One of the posters above was tracked down to their real name, home address and telephone number in about three minutes.

I do not use any techniques which are illegal or any fancy programs, I just use a few tools which are available to anyone.

here are some tips to keep your real identity a bit more anonymous.

1. always choose a new nickname when sigining up to any online service.

2. do not add any unnecessary information such as what country you're in or a 'my home page' address.

3. Never ever ever ever publish personal details ANYWHERE on the intrernet.

4. use a web proxy/anonymizer

I say this as a network security consultant with over two decades experience. There is no such thing as a safe web site.
