I could use your help!

I'm trying to customize the Welcome Email message. I read the FAQ on this at FAQ https://www.zen-cart.com/tutorials/index.php?article=20. I was surprised that the code has to be edited. While I know HTML, I don't know PHP.

Here's where I'm stuck...

PHP Code:
define('EMAIL_CONTACT', 'For help with any of our online services, please email the store-owner: <a href="mailto:' . STORE_OWNER_EMAIL_ADDRESS . '">'. STORE_OWNER_EMAIL_ADDRESS ." </a>\n\n"); 
I want to change the text to: 'For help with any of our services, contact us at [email protected]. We will respond within 24 hours to all inquiries.'

I don't want to use the default store owner email address. I'm not sure how to modify this to that it has the customize text. I'm sure it's a simple thing. I just don't know how to do it.

Thank you in advance for any assistance!
