As a service organization, ARIN places a premium on being responsive to the needs of the community.  Our ability to respond is heavily impacted by the level of community participation in elections, meetings, and the policy process.

As the ARIN community grows and changes, we are actively seeking to diversify community involvement through our outreach and education activities.  We rely on our members to be "good citizens" by voting in elections, attending meetings, and participating in the policy process, so we can continue to fulfill our mission.
