Jil Swinnerton - Associate Technical Editor
'Jils' (aka dictionary) has been part of Firewall.cx from the beginning. She undertakes the task of seeing that the material is published in a form of the English language that is comprehensible to all!
For those who remember the early days of the IT industry, you may recall the complexity of computer terminology before it became a part of life. To add to the confusion, Jil also has the difficult task of deciphering Chris's and other editorial member's language, one that is unknown to the human species!
Once a subject is thoroughly researched and documented, Jil endeavours to correct the spelling, grammar and formatting. This process is not always smooth when Chris takes the initiative to publish updated material without showing it to Jil :)
Sahir Hidayatullah - Security Advisor
Sahir joined the Firewall.cx team in 2003 as the site's Security Advisor and Forum Moderator. His contribution and expert advice to the site's forums and articles have captured everyone's attention and he has quickly become amongst the most respected people on Firewall.cx
Sahir programs in C/C++, Assembler and Perl, and had his first brush with networking 10 years ago over a 9600bps modem, connecting to local BBSs and subsequently he made network security his pet topic.

Review Team and Forum Moderators
Alan Drury (TheBishop)
Alan discovered Firewall.cx in early 2004 and has spent much time answering members’ questions on the forums and as a beta tester for our Cisco lab.
Having become hooked on electronics at an early age, Alan filled a mis-spent youth with a variety of projects including the construction of large PA systems, amateur radio transmitters, programmable stage lighting controllers and setting fire to the bedroom carpet (twice).
This led inevitably to an HND in Electrical and Electronic Engineering and four and a half years as a Transmitter Engineer with the BBC. From there he defected into Technical Authorship where he found himself explaining the intricacies of Ethernet, client-server applications and large network installations to a varied audience. Reasoning that if he could document it then he could do it, he switched careers again and landed a network engineering post at the UK's National Exhibition Centre. The rest, as they say, is history, and Alan currently works for a large multinational company supporting a complex national network.
Alan brings to Firewall.cx a wealth of practical experience and an engineering background that informs and illuminates across a variety of topics. In his spare time Alan enjoys hot and spicy food of all kinds, particularly Indian dishes, and has an insatiable appetite for Chris's olives. He is writing a series of novels, loves to listen to music and is an active member of his local church. One of these days he hopes to get round to doing his CCNA...
Wayne Murphy (Smurf)
Wayne graduated from Teeside University in Middlesbrough in 1997 with a degree in Computer Science. He has obtained an MCSE in Windows NT/2000/2003, CCNA, CCSP, CISSP, CEH, CWSE+ and is currently working towards his CCNP certification.
Initially, Wayne practised within the Microsoft arena but in the last 3 years he has extended to network security and network infrastructure. He says "I have recently begun working within the Security/Network arena and I am still enjoying the learning curve. The Security arena fascinates me and I really enjoy the new challenges this is bringing to my career."
Recently, Wayne completed successfully his CISSP (Certified Information Systems Security Professional) making him the only team member with this qualification!
He enjoys taking his motorbike out for runs, dining out (really likes Indian food), watching various TV series and, obviously, messing on his computer.
Dele Oyebande (Dalight)
Dele has had almost 15 years’ experience in the specification and development of ERP (Enterprise, Resource and Planning) systems. He combines that with a keen interest in networking and security issues as well as an unnatural enthusiasm for Open Source Software!
He is a qualified Electrical Engineer with expertise in the area of condition monitoring and the design of computer-controlled test equipment for use in manufacturing industry.
He is currently involved in projects utilizing content management systems to provide solutions for businesses.
Dele holds a Ph.D in Electrical Engineering.
Nikitas Skembris (Nske)
Nikita, joined the Firewall.cx Team in 2006 and is currently a student in Athens studying Political Science and History. However, despite his line of studies, Nikita's interest in computers arose in the mid nineties. Since then, his experience grew due to his envolvement in several community based projects on networking and security.
His knowledge of administration on Unix-like operating systems and related issues, as well as coding, is extensive and keeps growing. Like many, Nikita's knowledge has grown from experience rather than certifications, though this doesn't rule out the possibility of obtaining a degree in computer science.
Currently, Nikita works as a network administrator in an internet café, which aids in purchasing equipment for his expensive hobby and aims to conquer his CCNA certification in the near future!
John Watters (Rockape)
John has been a member of the Firewall.cx family since 2004. Typically you’ll find him inside the site’s forums, ensuring everything is running smoothly and people are not misbehaving :)
John works for an I.T. firm as a Network support engineer, however, his job also encompasses desktop support, certain software support and everything else the Unix and Oracle Teams don’t do.
To help prove John does have a life (unlike most of us!), is also a Civilian Instructor with the Air Training Corp and is the Chairman of the Parent/Teachers Association of his son’s (Isaac) School.
Ammar Muqaddas (S0lo)
Ammar has been a member of the Firewall.cx community since 2006 and accepted Firewall.cx's invitation to join the Site's Team in 2008 as a Forum Moderator.
