In principle there is not a problem with taking a percentage for the PPRuNe Fund, but what IFR was saying was rather different. He was offering a highly personal print to the highest bidder, with ALL the proceeds going to the fund.
Also, this has been discussed before, but to avoid an 'open' forum and the ensuing probable free-for-all it would have to be, by necessity, a very selective process. This in itself suggests that it won't work of course. We have also considered an online auction, and conducted a trial within PPRuNe, but it was not altogether successful.
However, since the fund is an important element in assisting wannabes perhaps a method could be evolved - but don't hold your breath, it is very complicated - as we have discovered.
