and have a mobile device, why not try a neat little application called 'Pocket Guardian'?
The software company involved - PC Tools - has asked us to ask you to try out the beta version of their new product. We're not endorsing the software or the company, although we've worked with them on numerous occasions, and know them to be a thoroughly professional business.
You can download Pocket Guardian if you click here
We'll be interested to hear what you think of it. I'm posting the same thread in Consumerwatch.
