I have noticed that some tones that I learn are wrong on Skritter. The problem is actually due to the tone usage differences from Taiwan to China. An example of this is 情形。 On Skritter they are requiring me to learn it as 形 having a neutral tone, where as my book and native speakers I have asked all use the the second tone. Is there a way to customize the tones?

When you see a word like this that should allow the full tone, use the feedback button in the lower right while practicing to let us know. In most cases, we can add an exception such that the full tone is allowed to satisfy Taiwan-style Mandarin.
