                                          Attend the Next Forum!
     For the last twelve years CPSB has had the pleasure of hosting a learning event
we call a Forum. We started offering programs in Sarasota in February in 1991 and
our first Forum was held in 1992 as a small group meeting.Being from the Northern
USA, this was a particularly good time to go south for the warmth of our friendships
with DR. Treffinger and Dr. Noller and to keep away from the cold winter.
     The Forum is the only chance to learn about various topics of the creativity and
innovation (革新) and from those who have rich experience and interest in the field.
The theme of the 2004 Forum includes searching for a few new methods, sharing
 lessons from experience, and learning and exchanging ideas on cutting-edge research.
Space is limited,so early registration (登记,注册) is welcome.
