Wow... Only me... That's disappointing...
Anyways, you have to spread word about your own competition yourself, not anyone else; its your responsibility. Or you can check on other competitions out here like the Arts skill Competition or the Haiku Contest on how to make a good competition yourself.
You could make your own story to kick start each round too...
Aaaand... the deal isn't sweet enough. If you send me a chocolate cake, I will reconsider ;)
