Mark has been performing systems and network design and administration since 1999, and has been involved with the Notacon network since NAC4. Unofficially placed in charge of the network for NAC5, he fully inherited the position a year later, at which point he began to introduce fundamental changes in how the network operated. For the rest of the year, Mark is the CIO of a medium sized ISP where he has been employed since 2004. His fortes include programming, system administration, and security, but his true love is networking. In his off time he is also an avid reader and historian.
