Write a review, then click the preview button. At the bottom of the preview, there is a Y or N selection with the caption, "Does this looks right?" Considering how grammar plays a role in reviews being accepted, it might be a good idea to fix that.
Then again, anyone smart enough to know better understands it's a typo, while the fucktards who would write sloppy, 8th grade level reviews probably wouldn't even notice.
Makes no difference to me, but thought I would mention it.
