Having worked with servers and the hardware end of IT with servers (where all the data is stored) before becoming a teacher our company started having similar "lag" issues in our early days as well and complaints from customers about our product not being unusable caused us to hit a dollar and cents wall. And it really boiled down to our company's faith in the product that we had created. We had faith, took the plunge and invested in more hardware and the company has since been successful enough to produce other wolrd wide products and hold yearly conventions to celebrate those products for years to come. Classcraft is a great product but I have not paid for premium service yet but have invited and taught my of my collegues how to use classcraft, but because of this lag problem I am considering other options. If the problem continues I am sure I will not be the only one who will dissapointedly walk away from what could have been an amazing product, if only it wouldn't lag all the time.
