University of Alberta Game Design course that uses Neverwinter Nights as it's engine.

The Neverwinter Nights Community Expansion Pack. This is a metric boatload of content for the game.

Neverwinter Nights wiki. Contains scads of community-editted information on the game from both a player's and builder's perspective.

A community-based NWScript Language Reference and Resource Guidefor Neverwinter Nights. Very comprehensive.

Neverwinter News, Trailers, Screenshots, Previews, Reviews, Guides, etc. Even though it's run by IGN, this place looks to have a good community for NWN builders.

A small collection of Neverwinter Nights portraits, usable in the game. Examining the rest of the gentleman's site will reveal more artwork, mostly sci-fi and fantasy, very detailed, feels pulpy. Site design sucks, though. Beware a barrage of windows.

A script generator (?) for Neverwinter Nights.
