The administrative panel is very accessible, easily configurable, and structurally sound. Clearly a fair amount of thought went into the design itself, as it's very user-friendly from an administrative and end-user point of view.
I'm still working on getting the reply by email plugin functioning, but support has been very responsive thus far!
Recommend this extension to anyone looking for a very reliable support ticket system - priced very reasonably.
The AJAX Registration page works perfectly, and has integrated with my template quite well. The added bonus of having security features such as Captcha also made this extension a huge A+ in my book!
Extension aside, the developer has been available 24/7. I've had a few technical questions in integrating a few ideas and also some general questions - questions were answered same night. Support provides real-time access behind a few chat programs (e.g. MSN)... I found this to be wonderful.
Thanks again for the great work! Keep it up!
