"I think that the quality of the English used on the Nike forums is bad."Some are saying "the Nike forums" is acceptable as there are many sub forums within the main forum, i.e. Nike Shoe discussion forum, Nike Clothing discussion forum, Football discussion forum., etc
Nike's forums, or Nike forums are are both ok but sentence structure changes a little: "I think that the quality of English used on the Nike forums is bad" "I think that the quality of English used on Nike's forums is bad". I imagine Nike forums being more commonly used. " In England, we don't say "the quality of the English", we would just say "the quality of English".
