We could eliminate the use of a block by just using signs like we are using now. They could offer a small 3x3x1 protection zone to ensure a player will not warp to his death.
Really like these ideas or nicks idea of just adding /warps i support
I dont wanna create a seperate thread cuz its so simmilar, but maybe /warps should be provided to registered cities, just like /warp northtown
you could use /warp (cityname) just a thought but it would really help developing cities i think
