I have done proofreading and testing for friends.  No list, unfortunately, which I realize leaves me as not the most attractive prospect.  But for what it is worth, the papers I proofread received pretty good grades; and my friends passed their classes.  I have also proofread and tested for several visual novels.  My focus is on grammar and technicalities/consistency.
