Each week there is a chance that a special prize might be added so submit every week just in case!

Sound good?

Depending on the difficulty of the challenges I'd increase the % a bit (if they were like I recommended I'd be hoping for more around 200%), but so long as they're achievable by everyone from newbies to pros, sounds nice
