As for my experience with the toolset, what I have to show for are these three mods I made for NWN2:
Clangeddin's UI: http://www.nexusmods.com/neverwinter2/mods/1012/?
Clangeddin's Rebuild: http://www.nexusmods.com/neverwinter2/mods/1010/?
Clangeddin's Fixes: http://www.nexusmods.com/neverwinter2/mods/1020/?
It may not be much, but it may be enough to prove that I'm not a complete amateur when it comes to NWN2's toolset and scripting. I am, however, a complete amateur when it comes to making new areas/models/weapons/creatures, so please don't ask me that.

Anyways, I'm willing to give a hand and make something for the server if everyone else agrees, maybe some of my mods could be even partially implemented in the server (if/where necessary).
For transparency, I'll say that I'm already on another Server's staff (Sigil: City of Doors), so if that is somehow against the rules, then disregard this post, as I don't plan on quitting them anytime soon.
