Well this seems pretty simple to me. When a competition is anounced read the rules, if you don't agree don't compete. When the overclockers are walking away from manufacturers competitions instead of competing hopefully they take notice.
So if I understand this correctly if I buy a top of the line setup today and a month later decide to sell to someone on my team that is not considered sharing. However if I am done benching with the hardware and decide to send it to someone to use because I upgraded and it is sitting around then we call that sharing. What about 2 people on the same team with identical hardware submitting benches. Is this sharing if the IM or phone each other to work through issues.
