There is no OFFICIAL posting competitiion. It was just a cheesey smart line. But if you enjoy Potter Posting, the years will go by in a flash. You'll see. Before you know it, you'll be able to pass your OWL's, apparate and get a job at the Ministry of Magic checking Percy Weasley's in-box for Fizzy Dung Bombs sent to him by Fred and George and earn enough galleons to buy your own Firebolt. The sky is the limit!
