Set sharing message and lead text

In the example setup of social sharing plugin on https://premium.wpmudev.org/blog/the-ultimate-viral-marketing-wordpress-plugin-yours-for-free/ there is no body-text below the headline (see http://screencast.com/t/2Zz2jM4z) but when I have clicked the button there is text below the headline (see http://screencast.com/t/wFInKCKrN2wV). How do I achieve this ? Whatever I do there is always text beneath the headline.

Also is it possible to set the message to share / like ? It seems the plugin uses the title of the page, but I would like to override this text
