Thanks for wanting to help send some notes of cheer and support to our troops. I'll try to get back with all of you ASAP, hopefully within a week. I still have dozens of requests I couldn't get to by Christmas. There is no "organization" here, just me and my computer.
I started writing the troops myself back in early 2003 when my niece, a Captain in the 18th Military Police, wrote home about some soldiers who were not getting any mail. (Hence, the "Aunt Nancy" name stuck.) Troops pass along other soldier names to me, sometimes one or two at a time, sometimes 20 to 50.
Several units are redeploying out of Iraq right now and I have very few new troops to assign at the moment. That can change overnight or, not for several weeks. Quinn & Rose's website has a few nice, larger, military-assisting websites you might have good success with. www.warroom.com
