Does anybody know if there's a list or guide that tells what the scripts Bioware has already made do? I'm slowly getting my own small list but having to open each of the scripts to read the headers is getting to be a pain.

There's about a dozen scripting guides on SP... Depending on what you need, you might find at least some of use: http://www.sorcerers.net/Games/NWN/index_toolset.htm

I don't think that guide quite does scripting justice IMHO, but I have seemingly found THE scripting guide. It's made by David Gaider with some help from Celorin (or something), it's very very good. Not only giving you the scripts, but also teaching you the scripting language as you go through the tutorial.
I have e-mailed it to you Capt.Tripps, and have sent it to SP for up-putting. :)

Thanks guys, not quite what I was asking for though. What I wanted to know is if there was a list of the Bioware scripts; ie. nw_o2_generalhigh - generates a random high treasure. nw_o2_generallow - generates a low treasure. That type of thing, sorry I wasn't clear on what I was looking for.

I doubt anyone bothered to make a list of those since you can pull them straight from the SP modules...
