The content on this site can be deadly to your computer! In short, "If it breaks, you get to keep both pieces."
These guides, HOWTOs, tips, and notes were written by people just like you. They have taken the trouble to write down how they did something. They are not in front of your computer, they don't know all the hidden "gotchas" that come with your computer, or how badly you screwed up your system trying to "do it yourself" before you decided to seek help. Nor do they need to. It's not their problem, it's yours. But we'll do our best to help you sort through them if we can.
