matt milton you have missed my point.
you matt milton[hypothetical]were intending or were half way through a series of field recordings,when you discover[shock horror]that a request to do a review arrives on your computer,and that you are requested to do a review of material,that another collector[a n other]has done ,he has interviewed the same people as you and finished the job before you.
so what you shouldnt do is do the review and slag it,integrity is required,
just say to the reviewer, ,my abilty to do an independent review has been compromised I can no longer do this review.
