If you have family and friends fighting overseas, you can chat with them courtesy of the US military, as long as you are using Windows that is. For a site intended to be used by mostly non-technical people, you would think they could afford to purchase a signed certificate from a known authority. Sure it's signed by "DOD CLASS 3 CA-7" with SHA1 and MD5 fingerprints, but Mom and Pop go glassy-eyed when I try to explain. The first call I received from my mother-in-law trying to chat with her daughter was "Unable to verify trusted site — what do I do?". Next call was "it doesn't work". OK, Safari doesn't work so on to Firefox. I can log in and change passwords in Firefox, but trying to chat brings up the error "You must use Netscape Navigator 7 or better". OK, download Navigator 9 (comparing apples to apples?) and get the same error. "You are using Netscape Navigator 5, you need Netscape Navigator 7 or better." Wrong, I'm definitely using Navigator 9, which IDs itself as Mozilla/5.0
The application is apparently Java, so what is the big deal? All a worried mother wants to do is chat with her daughter away from home in the desert."
