Applying a RS pin?

Hello,i am a middleman on another site and i was wondering how i apply a pin while middlemanning a trade?Say someone was buying a pin for 5 dollars and someone was selling,and i middlemanned,how would i apply the sellers pin to the buyer?

 

Sythe no longer endorses pin sales, so I would assume we no longer support pin MMing either.

 

you could do it for them by getting their user and pass and entering the pin that way. i'm not sure of any other ways.

 

Receive account
Change password
Get pin
Apply pin
Buy gives seller money
once this is confirmed you give pass to buyer

 

You just basically take the buyers account and apply the pin for him, if it works then you send the money to the seller...
