The whole table needs to be reworked. Because while Idealist Challenge is your idea, I am the one hosting it so I feel that the award icons are unnecessary. The rewards are +rep and even fladdermasken said that this isn't an official arena, the icons aren't official. I know you are making the icons and that each winner will have to put them in their signature, but I think that is a very fake way.
I'm considering it, but if you want to keep the icons then I take no responsibility for the +rep the icons give nor their creation.
