What does it mean by talking to other players underground, in Pokemon Diamond?

When I checked the Internet, the Internets says that to get a Spiritomb the player must:


1. Place the Odd Keystone in the tower.


2. Go into the underground and talk to other players a total of 32 times.


3. Return to the tower, and Spiritomb will appear.





I want to know if it means that I need to talk to the men who trade me goods or I need to talk to the other people who play Pokemon Diamond by connecting the Wi-fi.|||The hikers (goods/trap traders) do not count towards your 32 people.





You can only talk to people on local wireless - ie, if they are in the same room/area as you. They also have to be in the same section of the underground as you.


If you dug at Snowpoint, you won't be able to reach them under Twinleaf after all!





*A hint for getting to '32 people': If you have a friend with pokemon diamond/pearl, make your secret bases near each other. Then, talk to them, go into your base (block door), go out, and talk to them again - they will count as 'another' person!|||if you want get afriend to hook up with you underground


and just go up and down and talk to him then leave then go back down do this a total of 32 times and you will get spiritomb|||u need 2 talk 2 different real people using the wireless, not wifi.
