Larian Studios Forums General Chat RPG Chat NWN What MP modules are the best?

I have played NWN, but never finished it. I read a post somewhere that people who only played the official campaign had a mediocre opinion of the game; to truly enjoy the game one should play a good online MP module. OK. What MP modules are the best? In your recommendations please in mind that I do not own any of the 2 expansions, and don't plan to buy them unless of course I get hooked on the module thing. Also if you have a recommendation please specify exactly where I can get access to it. I've never played online before so any special tips are always helpful.
