The idea came up in another thread (about posting your crappy old tunes) to have a remix contest where you remix yourself. Take an old tune from when you were starting out and remix it (VIP it?). Start a soundcloud dropbox and post up the originals at the start of the contest, and the remixes at the end, most improvement wins. Could be a vote, could be judged, whatever.
I have to admit to not really having the time to moderate this, nor do I have any prizes to offer. If enough people are into this, is there like a forum protocol for setting this up?
