A typo in curriculum

I found a typo in Object Oriented Programming / Use inheritance so you don’t repeat yourself. There is unnecessary “is” in first paragraph.

Thank you for helping make FCC better. Bugs can be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.

As the sentence is structured, that ‘is’ is required. But I agree that the sentence is awkward.
