This gossip script lets players teleport to other players for a set amount of gold. When they use this item, a text box shows up, in which they input the name of the player they wish to port to. Then, if the rules allow it, they will port to his location.

This is the script you've seen in countless repacks and servers.

Can you add the Setup.h and Setup.cpp files?
