For those of you who want to show your support for the troops and don't really know how.
http://www.letssaythanks.com ^Really easy way to do it. You pick a postcard from the ones they have displayed. Then you can choose a pre-typed message or click on the "other" option to send a customized message saying thanks and whatnot for serving our country. Xerox will print it out and send it to the soldiers over seas. You can't pick which soldier it goes to, but it might go to one whose family does not support his/her choice to fight for our freedom, and does not receive any mail from them. Think of how good that would make said soldier feel.
Anyway, just thought I'd put it out there for those who are interested. It's free and easy, and it'll make you feel good.
