GM Technical Manual Discussion

Just wanted to highlight Rob's reposting of the GM Tech Manual discussion so we could get those interested to post in again:)

Ok here's a query to all the gms, as a gm what areas of trek tech do you see as 'confusing' in the technical understanding side of things and as the edept is slowly working and gathering ideas on what to fashion for a 'gm tech guide' so to speak what sorts of areas would you like explained?
:
: Note this does not have to do with specs but rather that lore or tech in trek which seems confusing to you and unclear.
