Another thing with the PiF's is that I know a lot of guys (myself included) have developed a 'been there, done that' attitude. I have given out hundreds of discs in my day.
I think that the members of this forum are now a lot more savvy, so they know how to download the projects without the need to set up a PiF chain.
Lastly, there haven't been that many new projects around here (I mean on the Star Wars front) that I'd consider starting a new PiF chain.
