Vendors and Owner's rights

[Pringles]

Jack, I finally had time to do some research on this. 

I used web.archive.org to find if there is anything written about how vendors worked back then (in 1999).
I searched in the waybackmachine http://uo.stratics.com and looked at a copy of uostratics.com from 25 january 1999.
There I found an explanation of how vendors work.

uostratics guide about vendors 25 jan. 1999

• Vendors will only be eligible to remain in the house if you are the owner or a friend, and will pack up automatically if their owner visits them and is not a friend. 
  

This is all I could find. Maybe someone else can find more information about this.
