It is the job of the property creator to weigh consensus, but generally: <ul><li>All opposing points of discussion should be addressed before creation occurs. If there is still disagreement, it is up to the property creator to consider the thoughtfulness and logic behind points of discussion (i.e., an opposing voice with no thought behind it should not block creation, but a single reasonable opposing voice against many supporters may do so).</li> <li>The creator themselves should remember their responsibility to participate. If they disagree with consensus support or opposition, they should first participate rather than make a judgement call.</li></ul></li> <li>The proposal was first made <b>over a week ago</b>.</li></ol> <p>If all conditions above are completed, the status of the proposal can be updated to <code>ready</code>.
