I will look at pulling something together later tomorrow for a CS, torn at the moment between XO, Medical Officer and Security Officer. I've experience with writing a security officer (and hey, Colonial Marines - there'd be no down side!), and writing a medical officer too, but it'd be nice to try something different in an XO. At the very least, I'll put together something with my mind all made up, and see what our esteemed GM has to say on the matter ;)
