A few weeks ago Chris Gammell (of The Amp Hour and more recently Contextual Electronics) has released his set of KiCAD videos, and set up a forum for users to discus the software, all available on the new kicad.info site. I've been using KiCAD for about 6 years now (I looked up my first PCB order I designed with it and it was September 2008) and whilst I happily recommend it to anyone who wants to get into PCB design, I've completely forgotten how complex it is to learn to use. I think the video series is a great starting point and the forums are a good way to troubleshoot specific issues you have. There are a good number of people on there now but the more people, the better the range of discussion. There are a couple of existing mailing lists for KiCAD, the developers mailing list on Launchpad and a users mailing list which is a Yahoo group that always gave me a really terrible user experience. The new forum is much more intuitive and interactive.
