A boatload of folks got the military signatures at http://militarysignatures.com
They now have some CAP stuff - missing most badges and wing patches but have most if not all ribbons and a few backgrounds.
I found some free ones here (http://www.myarmedforces.com/).
guys, please.. one or the other. Either a couple lines of text or a small graphic. a 10-line sig is lame.
