Major + Essay = Admission?

Should I include my intended major in my Common App Essay? Would it make a difference if it didn’t? Also, does anybody know of a place where I can have someone read my essays for free (other than my teacher)?

Once you get 15 or more posts, you can private message one or more of your essays to someone on CC willing to read & critique your essays.

I would be happy to offer a brief critique of one of your essays if you PM it to me.
