About the Reviewer

William England (WJE) started his professional IT background in 1991 after receiving training from a leading software house in Unix and Xenix before moving on to Microsoft Operating systems with the advent of Windows NT and further releases of Windows.

In 1995, William set up the IT and networking arm of William J England & Son Ltd, offering various IT-based services from installation, support and consultancy for local and overseas companies.

With the increasing need for e-mail and enhanced telecommunications William extended his area of expertise to GSM cellular distribution to complement the existing service level, together with e-mail and hosting solutions, anti spam, content security, and eventually VoIP.
