Since the beginning of the course, it was my intention to allow users to type a double vowel rather than a vowel with a macron (e.g. yy instead of ȳ). I assumed I had built this functionality in by stating that, for example, yy was an acceptable typo for ȳ. Apparently this wasn't so. Instead, I needed this to be added to the list of the language's "rules", something only Duolingo staff could do.

Well, the good news is that Duolingo staff has added the rules I requested as of a few days ago, and as of today, the rules actually function for users! This means from now on, for any exercise, you may type the sequences on the left instead of the characters/sequences on the right (upper or lower case):

• aa instead of ā
• ee instead of ē
• ii instead of ī
• oo instead of ō
• uu instead of ū
• yy instead of ȳ
• hr instead of rh

From now on, Duolingo will automatically replace the items on the left with the items on the right. This should make typing in the language a lot easier—especially for mobile users!

(Note: Due to the presence of nj and ny sequences, nothing can be done for ñ. Hopefully that character is common enough that it doesn't cause too many problems.)
