Hmmm ... To start: put a period after "writing or typing" (although I'm not sure if your first sentence is completely correct regarding the use of "English" -- as opposed to, say, French -- typing). At the end of your (now) second sentence: "I will welcome any corrections" might better state your intent than what you have written (unless you actually mean that those who correct you are welcome to come to your home for dinner and an overnight visit).
