Not sure how easy it is to keep a tally of votes and award some sort of star, medal, privilege or something to the profile? Also with the reviews it could be good to have a ratio of posts on your own songs/threads to other peoples... We all lead busy lives and its easy to slip on the selfless duties without some sort of reminder or indicator of shame/virtue.
Speaking of which. . . One of my duties as the manager of the contest is to find a replacement for next month. Is there any way I could implore you to take on that task? If you would do it, I could send you all my spreadsheets for comparing songs so that it would be easier (it isn't easy) to see how I do it. (Each person has their own method - and you would be free to use any method you wish.
It can be as simple as picking five songs you think are deserving AFTER you have determined who is eligible. When I do it, the first thing I do is make a list of ineligibles (those with fewer than 100 posts) so that I don't have to wade through every post for the last six weeks. THAT is the complex part.
After that, you are usually only left with about 15 songs to choose five nominees from. There will actually be about 20 songs eligible, but most will be duplicate entries from the same people, so you just pick the best one from each potential nominee, and then you are down to around 15 songs.
For me, the excruciating part is eliminating songs to get from the eligible 15 to the 5 nominees. It's dealing with people's babies (the songs) really, and it's an entirely arbitrary decision - so there is no way to hide behind a "process". It IS the person managing the contest who hurts feelings by not nominating a particular song.
But the value of the contests is huge. Well worth being a part of.
