I know, Els, I'm seeing that too. Everything that makes money on this server (baring missions) requires some form of trading. Some are longer than others, some go through Guard systems (made that mistake once with a Firefly ><), but over all, everything on the server, again, baring missions, requires trading.
I'll state it again, the POS system that Friday suggested seems to be the best bet to spruce up trading via FLHook, so long as it doesn't get it's face nerfed off like the mining mod did.
Oh, and Regular piracy does require trading if they steal the cargo from them like I do with my pirate transport. Because then you've gotta take it back and trade it to the station for credits, so...
