The application is hosted on a free machine offered by RedHat cloud and ..in terms of performance, doesn't do so good. However, since I've just finished it, I want to know what is your user experience feeling.
P.S: I've used a free edition of HighCharts (not using it for commercial purposes).
It would be nice to have a demo account to use to to see what you have done. I would like to give some feedback, but not if I need to register with an email address and other information.
