The Ten Words Format: The ten "words" must be in a numbered list, either manually or using the <ol> tags. They must not use names and be relatively vague as far as publically describing the person they are targeted at. Whether you want the person the word is directed at to know it is them is up to you. You can be detailed, vague, or a bit of both. It is recommended that you read through Ten Words and look at other entries to understand the format.
Theory: Ten words to Ten People allows you to say what you really want to say to the people you really want to say it to without causing too much damage to the relationship you have with them. The point is to be vague enough that it may not be related to the person it really is related to, while being specific enough that they may understand that it is them you are speaking to.
