I have noticed that if you have a tab after m)C) etc that causes an error for coursera.
You can have a colon in answers on leanpub but not coursera - maybe we should make that fail the check instead of just a warning
need a space after the question before the answers or you can get really strange leanpub output despite no errors on our check or on leanpub when rendering
m)C)etc that causes an error for coursera.
