New XKCD Forums

• A list of items is posted at the start of a round. Each item starts with 10 points. (Feel free to change this in following rounds if a round takes too long or ends too quickly, or if the number of items in the list is significantly smaller or larger than usual.)
• In each post, you must give 1 point to one item, and subtract 2 points from another item. (Label the items you've changed with "++" and "--" respectively next to them, for clarity in case someone messes up the maths or is ninja'd.)
• When an item reaches 0 points or less, it is taken off the list in the next post.
• When only one item is left with a positive number of points, that item is declared the winner. The poster who causes this may start the next round (they're free to leave that to the next poster if they can't think of a list).
• No double posting.
