About "Split Credit Card E-Mail Address" function

Hi,
Our Zen shop has 2 admins. I'd like to send the hidden CC number of new orders to my friend's and my email address for faster offline processing. I checked the "Split Credit Card E-Mail Address" function in Admin settings but noticed it accepted 1 email address only :( Is there any chance I make it to 2?
Thanks in advance.

If you are actually using v138a - You are asking for trouble due to the KNOWN vulnerabilities within

Right. You should be upgrading to a newer version ASAP. v1.3.8a has some serious well-known vulnerabilities, unfortunately.
There's no point doing further customization of your old version, when you REALLY need to be upgrading to a newer version.

And your credit card merchant account company probably won't be too happy if you're sending card info by email. You should instead use something that encrypts the card info, such as the Ceon Manual Card payment module. As an added bonus, it might have the built-in ability to send to multiple email accounts.

Oh, thanks for the advice. I'm upgrading it now :D
