If you're just getting started with NDS homebrew development then you should avoid PAlib, PAlib users and PAlib tutorials at all costs. They will give you bad advice and teach you programming methodologies which will hinder your progress and ensure that your projects are plagued with problems that will be nigh on impossible to fix.
However, with that said, I know of 1 former member who used PALIB and he was good and a good teacher on what he knew.. but that was back in the good old days.. So, use PALIB at your own risk!
