Keep looking, that is a feature that doesn't exist, like so many other features.Ah OK was going to try and help a mate run some cargo and split my profits with him. So was looking for credit trade.
I'm not sure if FD are planning a credit transfer facility at all. Main worry is online businesses popping up selling credits for cash (IRL).
Even so, a way to transfer goods between ships without abandoning and scooping would be nice. I'm pretty sure I've seen some NPC type 9's around which want commodities and all you need to do is fly near them to transfer for the Galaxy Average. Now, that's something that could work for business between cmdrs.

They're working on player wings right now....guess it will come with some form of credit transfer between pilots.
