Hi again - sorry it's been a while!
Really what I'm looking for is a manual (other than the Nova Bible, which I have read) that explains the best way to make storyline plugins for Nova, and a further explanation of how to use NCBs and what ones are used already. Also a list of what descs and misn numbers are already used, and if there is an 'accepted' use for desc numbers etc. eg for accept mission, cargo load text etc.
I have looked at a few plug-ins and tried to work out what they have used as a structure, but haven't seen any clear patterns.
I hope you know what I'm trying to say!
