"Rate this app" popup - how to do it?

I know that Prime31 has an “etcetera” plugin that may do this. Is there another way any of you are using to have people rate your game with a number of stars in a painless way?

Thank you,
Brian

I am just providing a link to the page. Meaning, I have a social page, a subset of the main menu. This page has links to Facebook, twitter and the iTunes address for the store. I prefer this for two reasons, it is not aggressive, as it just doesn’t randomly pop up and b, ascetics.

Of course I am using the www class for the btns.
