The organization you were when you launched the software, is not the same organization you will be a few years into using the software.  People may come and go and business needs may change.  This is why ArcLight offers training services to meet the needs of a changing organization.  Whether it be training to backfill for a colleague that has left the organization or some refresher administrative training for your whole team, ArcLight is equipped to provide on-site or remote training sessions and documentation that will meet your daily needs.
