I contacted WTI about customizing a feature of the plugin that would require integrating WTI Like Post Pro with another plugin. Within just a few hours they had responded to my inquiry and were gathering the information they needed to create the customization. Within just a few days, they had the customization fully functional, exactly to my specifications, and with detailed instructions for how to install the code modifications.
In nine years of building WordPress sites, I have NEVER dealt with a more responsive plugin developer. FIVE STARS ALL THE WAY!
