Change "thank you for your order"

default email response is "thank you for your order"
How do I change that?

Hello Joseph,
You can change that by going to EShop->System->Translation.
Sincerely, Giang

Thanks for the information. that page is useful for changing some of the other messages, but it seems that the email I had a problem with was coming from authorize.net and not joomdonation. I just turned off confirmation emails in authrize.net

Hi again Joseph,
I am a bit confused about the your problem. All payment methods from EShop should use same notification email. Please check again.
Sincerely, Giang
