Currently, if you COD mail somebody, your next mail by default switches to "Send Gold" and keeps the COD amount from your last mail. So let's say you send something COD to somebody for 3k Gold. Then, you start to send a normal mail to somebody...it KEEPS the $3k Gold filled out & defaults to "Send Gold". If you're not careful, you'll inadvertently send money to people you don't intend to.
