I've seen that site mentioned before and when I looked at it, it was probably 95% misinformation & bullshit. It might be okay if you want to talk about gear, sounds, and things like that but DEFINATELY don't rely on it for legal advice. The 'music law' section was especially horrible. A lot of dudes claiming to "know" all kinds of things about the laws and nearly every one of them posting wrong or inaccurate information. Some cats even claiming to be lawyers which was clearly bullshit to anyone who deals with music law on a regular basis.
Maybe things are better since I checked it out but I wouldn't put my money on it.
