www.preludecrazy.com is a good one... I think they are in the UK though... so some of the pages you have to do some conversions
www.preludeonline.com is supposedly a good message board... however they tell you they don't charge and that it's free, and then you register and they tell you that you have to pay to get access. :fawk:
http://www.ntpog.org is a good site, I've been to their help sections a couple times. :thumbup:
