There is a lot of rubbish being talked about pprune starting sponsorships. Pprune should not get involved in this, what's more it shouls remain free otherwise I believe you would see a steady decline in members.
As somebody financing my own flying training I would not be happy about putting money into a pot to finance other wannabes. Let's face it, we're not talking about a welfare fund for those on the breadline. You make a choice to pursue a flying career and should not rely on handouts from others.
