Can you switch http://www.servoy.com/mobile sign up app over to the new mobile technology it's supposed to be all about? It's ugly, it uses images for gradients and buttons, the markup is messy wicket output, the back and forward buttons allow for repeated signups, no auto-responder email goes out -- a 5th grader could have coded it.
It is not an app a major technology company releasing important mobile technology would possibly build. The same care that went into designing the webinar slides should be evident in the final product too! Embarrassing.
