Great

Simple, to the point. Very pleased.

What I like:
– Simple to install
– Looks smart, non intrusive
– Works
– Easy choosing which items you want vs don’t
– Small and doesn’t affect performance

I would give it a 5 star if:
– the email article to a friend has the blog exerpt
– there was a shortcode you could use (or generate) to add it to any page you want

Great plugin. Hope that it continues to be developed further!!
