The documentation on their website appears to be out of date (v4, using v5), however their support team are fantastic with excellent turnaround times. They even logged onto my server to assist with the installation and configuration.
Using Realtyna I hope to break into a new niche market for these kinds of sites, and I have every confidence in the product. Well done.
Thanks for your comment . For you information the Manual is updated now and you can download it via documentation and support links . (Version 5.x and higher)
