The forum has a wealth of knowledge but like everyone else has said there has been issues in the past and sometimes still. Basically drama, but if you can get past that the knowledge on there is pretty great for the S-series. I learned how to do a manual swap, rear disc swap, full suspension swap, I wrote a how to on how to swap 3rd gen PCMs all of which is on there. Tons of great builds, some very mechanically inclined people and a few guys who know stuff inside and out with turbo builds and even just basic troubleshooting.
They basically try to "break you in" initially to make sure you can take the garbage that gets spewed out there. As long as you don't backlash they pretty much know you're not going to add to the drama.
