Well, I don't think anybody gives grammar lessons really
Just use punctuation, capitalize letters that should be capitalized, and use a spell check and you'll be fine. Grammar doesn't need to be perfect, it just needs to be utilized in such a way as to make your sentences understandable. And by language translators, do you mean to say that English is not your first language? You live in Thunder Bay.
In any case, I don't think you need grammar lessons, just utilize what every English speaker already knows. When you think about it, punctuation is representative of how we speak. nobody speaks in long run on sentences and expects to be understood they don't shift directions entirely and not pause they don't join together disconnected thoughts without pauses of some sort or hesitation actually some people do but nobody understands them and they are put into mental institutions she knows she knows she knows that was a quotation from a show dexter there is a mental patient there who says she knows she knows she knows when hes in the same hospital room as detective batista as hes recovering from a stab wound
So yeah, just use punctuation and a spell check and most people will be fine with you.
