Since there's been a lot of talk about privacy and about how legal it is to go places etc, this is probably as good a time as any to make a small announcement of my own. I'm pretty happy with the profits I've made from trading Enderpearls for a while, and so now I'd like to share my wealth with you guys :)
Ok so all you people out there - go ahead and visit the enderfarm! The path there starts at the staircase from the obsidian spawning block. Ignore the sign I have placed, I'll remove it as soon as I log on. Just follow the one-wide path ( ^_______^ have fun ) and you'll see the monstrosity unfold in front of you. However, at the moment IT IS NOT FINISHED. There is a part of the platform covered in water, parts that are just bare and there's an ugly "ceiling". DO NOT TOUCH any of this. And DON'T EVEN THINK of going up the ladder. And obviously, DO NOT TAKE ANYTHING from the chests at the centre of the platform. You can look around, you can especially look at the Endermen, but you can't touch. Simple.
Anyway, about how to use it: Stand underneath the ceiling, around one block away from the edge of the ceiling. From there start looking at all the Endermen that collect there. When they start coming towards you they'll be stopped by the 2 high ceiling and will just gather in front of you. They will all die from a single punch and shower you with DAT 5 XP and a shitton of pearls. However, the odd Enderman will teleport on top of the ceiling, so be careful when you venture out of the safe zone. Also, some of them will teleport to the water placed on one side of the platform so you'll see the odd pearl on that side. Like I said, the thing is not complete so excuuuuuusee me for any inefficiency. Also if you die, your damn fault. I will not compensate you for any losses.
Currently, it takes around 15 minutes or so to get to around level 45 ish. That's not a great rate, but I'll be adding more spawning pads every so often. Once I'm happy with the rate, which is ideally level 0 to level 50 in less than 10 minutes, I'll add an enchanting room. I also have plans for making the farm more easily accessible than walking a tightrope above the literal void. Again, don't try to "surprise me" by doing these yourself, this is something that I want to do my myself and myself only.
tl;dr go to enderfarm, look at everything including the endermen and do not touch anything but the endermen or you are a jerk
I'll edit screenies in sometime.
