That may be a nice **rebase** exercise :smile:: In commit 107ee623d245f8fce30fa7f2d1103ab638a05a8b you removed the length validation and in commit 10fb0d91bd8dd7d799f28f8abdd36b433450cf60 you added it again. Just edit commit 107ee623d245f8fce30fa7f2d1103ab638a05a8b and remove your removal and edit 10fb0d91bd8dd7d799f28f8abdd36b433450cf60 to remove your addition.You may do it together with Ion, so he can learn something too. :wink:
