There are quite a number of milblogs on the Internet (blogs by or about military personnel) and we have been visited by many milbloggers. I believe that is the other channel besides Free Republic that provides many enlisted troops a window onto what we're doing.
Also, last year the DC Chapter had a big rally to counter a large anti-war gathering of the world's misfits on the National Mall. It was broadcast on CSpan and FR was one of the primary sponsors, along with Moving America Forward and some other groups. There, we had a booth for people to make video messages to the troops.
And, many, many WR patients come out to the street t meet us when we are outside the gates. They email and phone back to the guys in their units. So, word gets around.
There is a program called adopted-a-soldier, by which we the people can get into e-mail and snailmail exchanges with individual soldiers serving 'over there'. Sometimes they need minor items, to ease their situation, like new socks, or T-shirts, or boots. But sending things other than praise and admiration and heartfelt thanks is by no means required with adopt-a-soldier. I reccommend everyone who loves and stands in awe of our courageous soldiers and sailors to join the adopt-a-soldier program and get involved directly with support in that way. I believe their is a link at Rush's website, or ask and I'll get the addy to use for volunteering to adopt a soldier.
