Thank you for your order page.

I want to create a simple page in joomla that says "thank you for your order, we have received your payment and we will email you your proof with in the next 24 hours."

I know how to set up my paypal plug in to direct to a unique page on my site, by keying in this new pages URL. I don't know how to create this page with out creating a article and then making a menu to link to it. I do not want any where on my website to link to this "thank you for your order page" the only way I want my customer to see it is once they have paid online and been redirected there from paypal.

How can this be achieved?

You can create an article and use such link:
where 56 is the id of the article and article-alias is the article alias.

Thanks Nicolas, Just what I wanted to know. -Thanks for the ongoing assistance.
