The forum is managed by Curse, and it has been having major issues lately. Told someone who was a Minecraft Wiki admin, he asked the guy who manages the forum, and he confirmed it is going badly. Not only that, the starfishs who took over Minecraft Wiki decided to migrate it to their group wiki site, and in that broke so many things.
Edit: I finally realized what cauldrons can be used for (besides leather armor and water bottles). Back when they added Zombie Pigmen spawning from portals, they also added the feature that cauldrons slowly fill with water during rain when exposed to it. Then in The Redstone Update, they made Cauldrons output a signal relative to how full they are. Perhaps they could be used as manual-reset rain timers for some kind of hostile darkness mob farm?
