(Jimbly's server directory isn't open, so direct links are needed)
Notes: All of the known worlds at Jimbly's server can be accessed via his groundzero, which I linked above. I have all of gradual dime's worlds as well as many other misc worlds in my archive.
With these urls / worldsmarks, you'll have access to every currently known world.
There are a few worlds which are not listed here, however they are pretty basic and not worth looking into. If you for whatever reason still want them, message me on worlds and i'll give you them. Simply open the directories and look for the .world file that you want, and copy the path. Then paste the path into worldsmarks - change location to go to that world.
