Now in .org i have an island but my neighborhoods are mostly offline and most of them are beginners so i feel lonely , is it possible if i move my island to another place?
You could always join someone's coop and have them immediately kick you. When you start a new island you'll be in a new spot. Note: You will lose all of your items in the process. So store stuff in an enderchest.
You can't move your island without starting over, of you do restart your island you have to join a co-op to change the biome, or to actually move.
I'm wondering can i get my biome changed to Flower Forest? I always spawn in deep ocean or ocean or plain EDITED: I edited the Cold Taiga Into Flower Forest
There is a slim chance he will do any of this without a good reason to do so. You are best catching him online and asking if he can change your biome. I can almost guarantee he will not move your island.
