Thank you very much Marcus, appreciate the gesture.
Would also like to point out in some of the lessons 'U' is used, some use "Jij" and some use "Je", although all means 'You' (formal/informal), it can be confusing as in the same lesson all 3 are being used - 'Je weet hoe', 'jij of ik', 'was u daar'. I'm not exactly sure how the grammar work but will be a good feature to add in.
Hope you get the Dutch proofreader soon :)
We will make sure that the proofreader changes all sentences to use the form which is most commonly used so that there is a consistency to the lessons. Thank you once again and we will be sure to let you know when the quality has been improved.
