Question about re-submitting designs

Hello thar,

I’ve seen people use old designs that they spruce up or revamp. So I’m wondering about the rules of reusing a design. I would think that you couldn’t re-submit derby designs over and over, people wouldn’t want to be constantly seeing the same shirts over and over. But what about submitting for the daily shirts (non derby)? If you submit in the derby and don’t place, can you still submit it for a daily shirt? Or once submitted anywhere, is it a done deal, never to be submitted on woot again?

I’ve looked through the rules and chats and didn’t see much on this. Clarification please?
