1. Members posting complaints about ratings that are not their coasters. I think that if a designer cares about their coaster enough and is mature enough, they can post complaints for ratings of THEIR coasters. If it does not bug them, why should it bug you?
2. Members commenting on the rating complaint. Only the Rater, the designer and Mods/Admins should be given priviledges to post replies to the complained rate. We don't need members rating rates and causing more flame wars.
