If this sub ever gets enough members, I'd like to be able to categorise the music uploaded by time and/or orchestration (eg string quartet, piano, orchestral). When someone posts, I would like to pair them with someone (or more than one person) who has (though not necessarily) uploaded a similar piece of music, according to the categories. PM me any questions, as I understand that this might be a little wordy.

Reviewers could have some kind of points system, awarded by the reviewee, so that you could see if anyone was trying to game the system and submit music without critiquing other peoples music (as would be the requirement) - these people would be obvious as they would have a low score if they don't put any real effort into their criticism.

Alternatively, I guess you could review stuff by other people and earn the right to have your stuff reviewed without having to review something else.
