I mean you can, but you would have to extract the world file and use vanilla asset blocks. Then you would have to contact Bacon about wanting to transfer the world. You could also start making a world on the server if you choose to play on ILoveBacons, then go make a WorldBound claim. Once a WorldBound claim has been accepted by a server moderator, you have access to having back ups and if I am correct you can also download the world.
depends which type of process you're talking about... If world bound, there's a link to it, http://world.ilovebacons.com/login/members_area. you use your account forum name and just fill out the proper boxes it asks for. Wait for a moderator or someone of higher rank to approve of your claim.
