"powered by nopCommerce" for a custom web site

Hi,

To a client's website I will add some commerce modules. I am going to use nopCommerce's libraries(Core, Data, Services and Web.Framework) but I will not use at all the website of nopCommerce(Nop.Web). Also I will use a free plugin developed by nopCommerce team.

In this case do I have to put "powered by nopCommerce" on their website?

Regards

Someone should confirm this, but I believe that you should put "powered by nopcommerce" on every page or form that uses the Nopcommerce software, as indicated in the licence agreement here:

(1) all copies of the Program in Executable and Source Code form must, as a form of attribution of the original author, include on each user interface screen (i) the "powered by nopCommerce" text; and (2) all derivative works and copies of derivative works of the Covered Code in Executable and Source Code form must include on each user interface screen (i) the "powered by nopCommerce" text.

I imagine that if it is only a single page on the clients website that uses the nopcommerce modules, then it would only be that page that would require the text.  And if there are multiple pages powered by nopcommerce then it should be each of those multiple pages that displays the text.  

At least, this is my understanding of the licence agreement.
