Why on earth would you want to limit appraisals to strictly Exclusive members. The more appraisals you can get the better.
See, "Exclusive" used to be a club that we paid $400 to join (at least, I did) and as such it had several great benefits over other types of membership, most of which have since lapsed or removed.
Added benefits should be in the way of tools and what not, not by limiting information which goes against the whole idea of sharing information on a forum. You hardly get many appraisals in the main Appraisal forum these days. Can you imagine the number of responses you would get limiting it to Exclusives.
I would say, Exclusive are elite members, therefore their opinions bear great weight.
Regarding limitations, it is limiting for other non-exclusives because they can't view the private appraisals.
