I love how easy this site makes things like creating quizzes, surveys or even just sending out emails to your customers very straightforwardly with no fuss at all (it really does make everything so much easier). The layout could be more intuitive but other than some minor issues in terms of navigation which are easily fixed there isn't anything major about noodle factory itself - you'll get used quickly enough if they're not what exactly YOU want them too do :) We've been using their services quite extensively over here during our training sessions both online & offline since we started working together last year now; from teaching people basic concepts such us HTML/CSS etc., through building websites via wordpress / drupal CMSs up till handling complex e-commerce solutions involving multiple payment gateways including Stripe + Braintree APIs amongst others.
