  • Promotes the teaching, learning and using of Smalltalk
  • Supports publishing and sharing books
  • Supports local users groups and establishment of new ones
  • Supports exchange and collaboration between students, researchers, innovators and practitioners
  • Organizes a yearly conference, school and workshop
