This extension is very useful and does a good job, but I am most impressed with professionalism and speed of the customer service. They held our help and answered all our questions in a knowledgeable, courteous manner event when it became obvious that our problem was not caused by their software. Their knowledge of their software real life application and case studies was so deep that they were able to point us in the right direction to solve our (not their) problem that caused DT Register not to give the result we wanted. I would shake their hand if I could! Keep up the good work!
