Celebrate! This still works 5 updates later, in version 1.8! Let's keep this thread alive!
In the 1.3 update, Notch added seeds for the World Generator, and now I plan to use this feature to its fullest potential. Join me and together we can experience the same world together in which we explore and familiarize ourselves with.
When a world is seeded, it generates the world based on the set you numbers you type in, and anyone that uses the same set of numbers will have the same world. That's why I we're using the numbers 7896, because then we will be able to explore the world together.
To begin your adventure, update your client to 1.8 and create a new world. You can name the world anything you want, I decided to appropriately name the world after the title of this thread. What makes this world unique is giving it the specific seed number. So click "More World Options...", as shown in the following picture.
Then, type "7896" without the quotes into the World Seed bar. Make sure there are no spaces or anything other than the numbers 7896 in the world generator seed. Also, it's important you keep "Generate Structures" ON:
Then hit "Create New World" and make sure not to move from your spawn point.
If you did everything properly, check to see if your render distance is on far, then turn to your right. You should be able to see the following NPC Village in the distance:
Congratulations, you can now begin your adventure along side fellow Minecraftians! Make sure to post anything interesting you discovered. If you are the first to find something interesting you can name it whatever you want, but please keep it appropriate. You can post anything you want, it doesn't have to be something you discovered, just as long as it's relevant to seed 7896.
IMPORTANT: To share something you discovered, press F3 and give the X, Y, and Z coordinates. This will also allow you to find things that others have discovered. This is also a great way to see if you're in the right seed, as it will say so right below the coordinates:
I found the village near spawn, so I decided I'll name it "Spawn Village":
Name: Spawn Village
Coordinates: x: -192 y: 69 z: 246
Discovered by: Qualjak
Description: The village very close to spawn, this is a great starting point because there's wheat, torches, wood, and shelter from monsters.
Picture(if there is one): Spawn Village
