(Note: I didn't want to go through approving this in COT for the purpose that it most likely wouldn't be approved as it can get more spammy than the "describe the sig of ther poster above you" game there. I also didn't want COT to be confronted with the spam even if a Forum Leader has approved it. I wanted to keep it here where I can easily moderate it [along with the blog staff if needed] and where spam is allowed anyway.)
