@phase Just view the html source of the page, everything but the player list is there
It just reloads the image bisect provides every 20 seconds. To change it you'd have to read the player count from the image, or query the server itself
@Deusovi Adding more villagers to the farm won't increase iron output (at least not by much). It's true that more populous villages can spawn more golems, but afaik, the rate of golem spawning cannot be increased. The golems in our farm are killed right away so we never really need more than one at a time.
