Even though this European day was a great success, and the informal European group very enthusiastic, the co-operation stayed informal. It wasn’t until 1991 at a meeting held at the European Commission, which included simultaneous translation, that the organization started making some organizational progress. The representatives discussed the formalization of the group and the evolving financial and constitutional issues.
In 1991, National association theatre nurses began to produce the European Newsletters to be circulated all over Europe. At that time, there were 16 member countries in the European group.
