I am holding a building contest for 10 stacks of diamond blocks. You can go to the forum and post a link at the forum to maximum 3 screenshots of the same structure in your lot. I will then make a pre-selection for the finalists (5 to 3, depending on how many people submit) and then let the users vote on who is the best. Further details in the forum post.
(If I catch someone selling/buying votes all involved people will be banned)
