Each member of the crew has one of four basic character types: 
Dominant, Submissive, Silly and Serious. Handling the individual
should be done carefully, so insulting them is not a good idea. 
Even a little charm can prove disastrous. And yes, I know what 
you're thinking, "Maybe if I used a little charm on a young 
lady I'd get a little action." I'm afraid not, I already tried
it. Well I suppose you'll save yourself a few seconds there 
(what, twice!). If the character seems submissive (Malichek),
you should issue a command, eg "Give me the Radiation Report".
However, if the character is quite dominant (Dr Luvey), rather
than being forceful and sounding like an arrogant prat, you 
should talkin a friendly manner.
