Tip: for answers, "wiki, wiki!"
 

What's a "Wiki?" It's an on-line, international, free encyclopedia. You can search it, read it, and add to it.

http://wiki.linuxquestions.org is a Linux-specific Wiki maintained by this site.

There's also a worldwide http://www.wikipedia.org that's entirely general.

Check it out! The questions you may have, may have been thoroughly answered there!

Not forgetting "Tutotrials, Tutorials" of course :)
