I've done tons of modding in NWN. Its what I did in my off hours from work for fun. I did this for three years. Click on my link below for one of modules.
I've done two projects in University with NWN and in both classes I got an A.
One was my breakdown of the Toolset at luckyday.nevault.ign.com.
The other was a team I headed to make a Rome based mod (actually two mods). That has tns of documentation as was required for the class

.
I've got a number of scripts posted on the vault but most of my best scripts I haven't put up yet. I have no idea why.
I have part 1 of a Star Trek mod finished but it got somewhat borked by a patch or two. I need to fix it then put a final cutscene in.
NWN2 I won't have time to play with as the semester has just started.
