How to show most recent e-newsletter in my site?

Hi!
I want to show a most recent e-newsletter in my site.
Because, that will be sample to my customer.

I know, the e-Newsletter plugin has the function that all newsletters already send could be shown in browser.
*like follow URL.
http://ex.com/?view_newsletter=1&view_newsletter_code=xxxx&view_newsletter_send_id=xxx

But,Using this way, I have to fill the "view_newsletter_code" and "view_newsletter_send_id" every time.

I want to do so more simply.
Does the plugin have the function that showing a most recent e-newsletter to user simply?

Thanks, Koji
