Don't hesitate to punctuate!
Is grammar and punctuation important? People forget how using complete sentences and punctuation leads the eyes and mind of the reader. How else will they get your point? If someone was speaking to you, their voice intonation helps them get their message across. With the written word, you need to use clear sentences that make sense along with punctuation. Otherwise, the reader's mind gets tired trying work out what you want to say and they stop listening to you. Miss out the punctuation.... have rambling, endless sentences ,,,, and you miss out on reaching the people you want to reach. You are sentencing your sentences to the graveyard and the delete button.
