Just an FYI to all, gunwatcher isn't making any money off his site, and he's offering it as a service to the gun owning community.
I hope this is incorrect as otherwise it won't be around very long unless he's independently wealthy. I suspect there are some advertising referral fees that might eventually come back to him since there are doubleclick.net scripts on the page.
I sure hope he can make enough with it to keep it going.
