Add the following to the list of Upgrade Criteria in the rule Upgrades:

* Post three consecutive Snaps each of which was posted at the earliest possible point (to the nearest day) that they could have been under the poster’s Development Interval at the time of posting
* A Snap which was provably taken in a different time zone from a previous Snap taken by the same Seeker
* A Snap, posted after 19 April, to which the Observer has responded saying that he finds it aesthetically pleasing (for the purposes of the rule No Cooperations, this may be considered a co-operative mechanism, although the Observer is encouraged to evaluate each Snap on its aesthetic merits rather than persuing any actual tacit or explicit co-operation)
