They have been amazing and worked with me to diagnose a problem I was having with the calendar - which ended up being something to do with the website I had installed it on rather than an issue with the product itself! They were extremely kind and patient, and I would definitely recommend investing in ANY of their products!!
I was having display issues with the default joomla faq and I found this one and it works a treat, I am very happy with it.
I downloaded the plugin version, and had a small problem with the display (which was related to my website host and not the plugin) and the plugin creator was extremely kind and answered my forum post within 24 hours. Now my FAQ looks spiffy as! Great service =) very happy
