I'll add this: Do the same for your own characters. It is horribly OORP to have a "trader" character that lives only to be the financial life-support system for your "fun" character. If you can't make money in-character then your character should be RPed as poor. Pirate? Do some smuggling on the side. Lawful? Trade on the side. Keep player knowledge and charcter knowledge separate.
I go by abbamouse, but my characters are the Cryer researcher Daniel Moss, the very boring and ordinary trader John Smith, the borderline-insane civilian Mr Joker, and a Bundschuh activist who goes by the alias Rosa Luxemburg. I am not them and they are not me.
