Perhaps your OCL friends should become a little bit more involved and find out that in many places, the various jursdictions worship together several times each year (in the Chicago area alone we have Sunday of Orthodoxy, Pan-Orthodox Thanksgiving Eve Liturgy and a Pan Orthodox Akathist during Great Lent every year. These activities are very well attended. Other areas in the midwest have various activities as well. Though there is virtually zero attendance from the OCL leadership in Chicago at any pan-Orthodox event.
Furthermore there is a group called Synergy, which is a pan-Orthodox clergy and lay organization which sponsors many events and most especially a Symposium each year in the fall. Add to that pan-Orthodox groups with the blessings of the local hierarchs such as Orthodox Christians for Life. Additionally there are pan-Orthodox clergy association in the Chicago area, Wisconsin, Northwest Indiana.
Just because OCL members do not participate, does not mean that the coordinated efforts and activities do not exist. They are done within the Church not as a para-ecclesiastical organization which seeks to reform from outside of the Church.
Just an observation.
