Super User, part of 
Stack Exchange , is a Q&A site for computer enthusiasts that's free. Free to ask questions, free to answer questions, free to read, free to index, built with plain old HTML, no fake rot13 text on the home page, no scammy google-cloaking tactics, no salespeople, no JavaScript windows dropping down in front of the answer asking for $12.95 to go away. You can register if you want to collect karma and win valuable flair that will appear next to your name, but otherwise, it's just free. And fast. Very, very fast.... More Info »
We don't run Super User. You do. Super User is collaboratively built and maintained by your fellow users. Once the system learns to trust you, youll be able to edit anything, much like Wikipedia. With your help, we can build good answers to every question a power user might have. No matter what operating system you choose, or what hardware you run it on, we can learn from each other.
Super User is as frictionless and painless to use as we could make it. We believe finding the right answer to those hardware and software questions should be as easy as falling into the pit of success. And maybe even a little fun along the way.
