Heigh,
I think quality control is a good idea - especially for novices. Even if it's just few exerienced people or one moderator who can take a look before posting a contest.
Going back to fool with this one after I posted it, I noticed there are some spots that cause plates to just pop in their own. I have not idea why, but someone with experience will probably know.
I attached an example of this if anyone has the time to look at it, I'd appreciate the benefit of your experience.
