It occurred to me that new members might not realize what a "boot chain" is.
Basically, someone with a lot of shows makes copies of those shows. People who want copies of those shows sign up for the "chain".
The originator of the chain organizes a list of people wanting to participate, and sends the shows to the first person on the list. That person copies any of the shows they want, and then sends them on to the next person on the list, and so on until the last person receives the shows. Being the last person, that person lucks out and gets to "keep" the shows . . .
