Sorry to ask the questions, but because I'm not familiar with license (and English, too) so:

In the license you said:

...

subject to the following conditions:

The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

...

So the questions are:

1) What is exactly the "copyright notice and this permission notice" contain?

2) What do you mean by "included"? I need to have it at the footer of every page in the portal, or need to have an "about page" or something?

3) Can I translated the copyright notice to my language or have to leave it in English?

Thanks in advance

Sebastian is correct, you must leave the copyright statement in the source code of the project, at the top of each codebehind and class file you'll see the copyright statement

My assumption, though it's just an assumption, is that you should leave it in English as translation may effect the meaning of the copyright statement.

Thank you for your answers, but in the case that I only delivered PA to the customer, how do I put the license in?
