Any military or former military knows what a shadowbox is. I mentioned the togetherweserved.com website to a couple former military types and said I’d post the link to mine here. So here it is.
The togetherweserved.com site is just that, different branches of the military and different ships and stations and organizations. You post the places you’ve been assigned, for example a ship, then when others from that ship sign up you can get back in touch with them. They have a free join and a pay one. Depends on what you want.
