I have received a few emails like RED FRIDAY and other like this. The Red Friday asks you to wear red on Fridays to show you care. Snopes said it was an active deal but hard to confirm if it had a lot of confirmable origin but also said basically that it seemed real. The same page gave me a link to a message board with an Army logo that does offer a way to send a quick thank you to our troops. The link to this is here
