Anglesmith
Setting up the play?
Google translate did all the work.
But it would be es because proyecto is masculine.
Incorrect. Estar and ser are two infinitives that both mean "to be" in English (ie when conjugated, they mean "is"). The difference between their usage is based (mostly) on whether the thing being described is in a temporary or permanent state of being. At least from what I remember.
For example, "yo soy Anglesmith, estoy en Victoria."
