I'll try to do some judging of this round during the weekend -- it's only 5 tracks, perhaps I'll do something different this time around, like a blog post highlighting the tracks?
Posting the winners in a blog is an excellent idea - that way they get attention on the home page without cramming up the News section. Announcing the next MTC could also be done in such a manner to grab attention - perhaps the two could even intertwine? ("Results for MTC February is out | Join MTC April!")
