The NASA Digital Learning Network™ website was part of the NASA Education Office's online services provided to teachers and students.  I originated, designed, and maintained the site as the DLN Project Manager during its 12-year period of operation.  The site was used by the 10 DLN™ studios at NASA field centers to inform educators about distance learning sessions and to assist them in scheduling live events with agency education specialists, astronauts, scientists, and engineers.  The DLN was part of the NASA LEARN Project.
