Aside from that PM I sent you-
I would like to see normal users given the option to disable PM's as well as a way to remove their user page header.
I also have a cute idea for the review system - It might motivate people to write better reviews, and if they've never wrote one this might encourage them to start:
If we had a review rating system, similar to the way the whistle stats work.
Say users are undecided on a review a user posts, this won't weigh either way on their review scale. Say a user writes a review which people think isn't useful, this will throw them back a couple notches on the scale depending on how many are in agreement( I'll get to how I think it should work last). If users think their review is helpful they will gain points towards being a five star reviewer and up.
Users gain points, or lose points depending on how many peers are in agreement with weather or not the review is helpful or lousy UP TO FIVE POINTS PER REVIEW. Meaning users can either gain or lose UP TO BUT NOT NECESSARILY five points per review.
There will be nine reviewer levels, no stars, one star, two stars, three stars, four stars, five stars, then five bronze, five silver, and five golden.
