Okay guys, this is what he means by this. Let's say that an admin is busy building somewhere and does not want to leave his spot, or he has a secret spot somewhere that he could easily lose sight of: He can use these commands to just teleport one person to the other without the admin leaving his current position. Do you guys get it now?
Let's say there are three people in your server. You, Blockhead and Faggot. With find/fetch, to teleport Blockhead to Faggot you'd need to teleport to one of them first. With this you can just teleport blockhead to faggot without needing to be there yourself, ya big silly head.
