Don't Allow Reviewer To Review Own Proposals
Right now, someone who is on review committee can see the internal comments of other reviewers to their proposal, a luxury that non-reviewer are not provided. Also, reviewers typically vote 0 on their sessions to show integrity.
It would be better to not even allow a person's proposals to be shown/accessed/available to them if at all possible .... obviously might cause some issues for track leads but there are others on the track that can help. Kind of a step-out-of-the-room-while-you-talk-about-me approach.
