The Dog Tag Project was started by Matt Freeman, a former executive at Here! media. The project's aim is to put names and faces on the fight against Don't Ask Don't Tell. They have teamed up with various former military personnel who have been discharged by the military under Don't Ask Don't Tell, and they sell replicas of the dog tags of those people (including Dan Choi).
We brought some dog tags to Cologne for the Gay Games to spread the word about the project, and the athletes there were excited to wear the tags. You can see several photos here; And you can buy your own dog tag replicas from the Project; proceeds benefit groups fighting Don't Ask Don't Tell.
