I found four, yes FOUR, spawners all right next to each other. I am going to make them into a huge exp farm. =)

Uploaded a picture with my debug screen on so you can see:

- The 100+ mobs after not even 7 minutes of "afk"! I didn't even get to finish eating my dinner.
- World seed
- Co-ordinates for the spawners (or at least, with in 20 meters of them)
- The version of Minecraft this world was generated on.

If you have any questions, comments, etc... please post them and I'll do my best to reply!

NOTE:
When I release a download for this, please make sure to check on your Minecraft every 5-10 minutes or so. Yesterday I sat in my XP farm and then went to watch a YouTube video and forgot about it for about 20 minutes. I came back to over 400 mobs! It made my computer lag so bad I had to turn it to peaceful to get rid of them all... Shame that over 400 zombies and skeletons had to go to waste.

Additional Notes

• "Hax or just Epicness?"
  

Just epicness... This entire world has been, is, and will remain 100% legit. I have no plans of ever using any mods or cheats in this world!

• I will be releasing a download for this world soon(ish)!
  

I am working on a couple of other things in the world before I release it.
