How can i visit an island when the owner is offline

[sabplay_]

My friend has set up a shop and he isnt always online, I like to go the to sell my items but I have to keep waiting for him to come online.
Is there any way to visit his island when he is offline

You can ask your friend to set an island warp by using the /is setwarp <warpname> command, you'll be able to access his island by using the /is visit command or through the /is warps interface, even when he is offline.
