How do I become a Senior Member?
Senior Members of deviantART are selected by the Director of Community Operations ($fourteenthstar), after reviewing suggestions made by the community with other full time deviantART Staff. Announcements are made on a quarterly basis and during special, celebratory events such as our birthday.
So what does it take to become a Senior? That's a question many have asked and have never really been able to get a straight answer on. Some have gained Seniority as a thank you for their time spent as a Volunteer, or to recognise their contribution to a particular project or collaborative action. Some have gained Seniority because of their community spirit, providing help and assistance to many other deviants and taking time out to promote the work of others in the community.
Some people have received Seniority because of their artistic endeavour, having a positive influence on their peers by sharing resources, providing constructive criticism and by being a voice that stands out above the many others who deviate to be recognised in the crowd.
If you come across someone who you believe should be considered for Seniority in our community, please note $fourteenthstar with your suggestion.
