I'm doing the math for the comp. Yes it has divisions. They are all visible on the results page (
www.ka72.com/Competitions/ResultsPage/GroupId/48 )
Note that page is showing last November's results until the competition starts.
As for prizes, the sponsor is providing prizes, but the guy organizing it is overseas on holidays at the moment so I don't have any information on what they are. KA72 will be kicking in some random participation goodies, not based on results, so anyone in the competition is in the running. These will be announced about halfway through the month.
