CDSG Forum

The old Coast Defense Forum was a online group for discussion of the history of the coast defenses of the United States and other countries, but is now gone with the changing times. We are now using groups.io for our forum which was the old coast defense yahoo group.

The NEW CDSG Forum is coastdefense@groups.io. Click the link below to join.

The CDSG also has a facebook page (https://www.facebook.com/cdsgorg/)

These are sites for posting and exchanging information, questions, answers, photos and events. Join one or both!
