I don't know how to make a seed so I done the next best thing because my daughter & I love the treehouse we made together so we wanted to share it with you all.So I made my Tree House into a rar file & uploaded it to share with all my Minecraft friends. I'm also adding pictures with this link so you can see what it looks like. in order to be able to play on that one you open the %appdata% click Roaming & then click on .minecraft , from that folder click on the Saves folder, Extract the Tree House.rar to the saves folder , close it then launch the game like you regularly would & the Tree House world should be in your listing without over riding any of your own. Please enjoy. http://www.megafileu...-House-rar.html . Here are the images of the Tree House, I do have to add , it is VERY high up in the air & VERY large. http://i92.photobuck...zpse34e599f.jpg
