- Getting confused between instance-side and class-side, mixing up which side methods are on. When getting a DNU maybe check if that message is known on the class-side. - leaving out the end of statement trailing dot. An error message like "Blah doesn't understand self" is a bit complex for a beginner to decipher. cheers -ben
