The Georgia Department of Education has hauled its former Webmaster into court, claiming he threatened to sabotage the state agency’s presence on the Internet.

Lawyers for the department said that the former Webmaster, Efrain Rodriguez, owns the domain name for the department’s Web site, www.gadoe.org, which attracts 300,000 visitors a month. They said that Rodriguez threatened to reroute traffic from the site to another address unless the department purchased the domain name from him for an unspecified amount.
