Override question admin or public html

In Reference to this tutorial:
https://www.zen-cart.com/tutorials/index.php?article=36

Do I do this in the admin folder or the public html folder?
I have languages/english in each of these areas. My zencart is inthe public html.

Only in the store section. There are no overrides in the admin area.

Unless instructions specify that something is to be done in your admin, you would work with the base /includes/whatever/ folders. Admin language file changes will not apply to the storefront.

Thanks again gj! I thought this is where it went.
I have actually looked to hire someone just for the customization part and have had 6 wonderful scam emails. One even said, he'd do it cheap, just give him the checking account number and credit card and he'd get right on it! Gotta love it!

Right, no problem, sounds like a good idea:)

The pros who help out in the forum generally have a link to their website in their sig, and any of them would probably be able to reliably do what you want.
