Space D20 RPG idea: I need new crew position ideas? Help! Please! Help!?

[Allice]

Hi, Ive been running a D20 which started out with five people (Captain, 1st mate, piolet, mechanic, doctor) and has sence then become very popular, with many more people wanting to play.

I am in horrible need of more positions for people on a small space ship. I have sence gathered a : hit-man, salesman-like person who stays on ship because it travels to different places where he can try and sell his wares, and cook (we're becoming despret).

The ship is a small, independent vessle that mostly serves as a ship running jumping between two warring systems, mostly smuggling weapons and meds. However, the ship itself does not have any weapons (its part of the fun, actualy).

I have found that people realy like to be the "only" whatever. For example, I tried two mechanics and two piolots, but people hated it. People also realy want their characters to have a purpus.

Now I am in despret need of more possible possitions as more players wish to join. Any ideas? Plz!!! Thanks!
