Missing translation string

Hello there,
I’ve helped with the Italian translation of Subscribe to Comments Reloaded, and I’ve just installed it on my site.

I am setting up all the options and notification messages, and I have just noticed that there is a missing string in the translation. Or at least I couldn’t find it in the Italian translation page.

The One Click Unsubscribe message still comes with the English content, and I also see that there are a couple of misspelling:

Your are not longer subscribe to the post:
<h3>[post_title]</h3>
&nbsp;

should be

You are no longer subscribed to the post:
<h3>[post_title]</h3>
&nbsp;

Looking forward to translating this string too.

Thank you in advance,
Marco
