IMEKO TC1 has started a series of On Line (virtual) Workshops and a Portal for joint use of educational material. The aim of this activity is to help educators in organizing good co-operation and getting benefit in their work. These methods give new possibilities to other TC's, too. It is possible to create a scheme of "distant participation" for scientists living in areas where it is difficult to travel to IMEKO symposia. The Workshops and the Portal can also help in finding co-operation partners in the scientific work. The paper presents experience from the first Workshops and discusses needs, difficulties and methods in development of networking.
