But you really should learn to punctuate. This isn't optional. The first letter of a sentence is capitalised, and you must use the right spacing around periods and commas.
I've noticed this a lot in posts from Arabic speakers. And I've asked this question before, but haven't received an answer - Aren't you taught about punctuation? How do you become this proficient in English without learning how to put a space around a comma?
(I'd be grateful if anyone could answer this).
