Wikipedia:Consensus statement

A consensus statement must ideally be made immediately at the moment you make an action, and explain why you took that action.

A consensus statement ideally has 4 components. These can be explicit, or they can be woven into the style of your reply (might be nice to make it nearly invisible). Sometimes not all are needed, though people should be able to ask you about any of these elements if you skipped them. Make sure you know the answers to all these components before you hit "submit" The components are:
 * 1) A personal reason why you are in support of the action you are taking
 * 2) What would theoretically needs to be said or done to make you reverse that position
 * 3) A reason why you think others (will) support you (i.e., why is this likely to gain consensus)
 * 4) What likely would need to be said or done to reverse the position of the community.
