When a visitor decides to "Contact the Listing Owner" is there a stat shown anywhere that let's them know how many times they've been contacted via the site or is just the email? Could this be added to show under account statistics?
No, there is no option for this built into the theme itself, however there is a plugin available in the AppThemes marketplace called contact stats which can offer some stats, you may like to review the marketplace page for more information. Thanks.
