Vern Six and Fritz Nordengren--two former military men--came up with this site to let troops overseas know someone back home is thinking of them. It does cost $1.99 to send a message, with $1 of that going to the USO.
You can view messages already sent to see what others are saying to the troops. If you know someone specific to send it to, fill them in as the recipient or you can send your message to any member of a specific branch or to anyone in general.
For this week in geek, I'm Mark Avery.
