Person A sends a fan edit/preservation to Person B.
Person A posts in the designated thread (or new site if Jay won't allow it, there are free forum hosting sites) that Person B now has to send that particular fan edit/preservation to the next 2 or 3 (depending on the set number we all agree on) people who request it from them.
Then Person B posts in the same thread that they sent it to Person C and that they must now do the same thing.
This way there can be no leeching because it will be reported that someone refused to pif and noone else would ever send them anything.
Also for those with slow connections, a physical pif could be integrated into the ftp system, you get one in the mail, the fact that you got one is posted online, you send out two in the mail, that fact is posted online, and those people continue the pif through ftp.
Am I crazy? Does anyone else think this will work?
