When I first started using Linux, I came to the table with a grounding in old command line Unix, and a few solid years under my belt managing a couple of Ultrix boxes where I used to work.
So I knew the basic set of commands, the Bourne Shell (or the basics of it, at least), and the general architecture the more Unix-like distros follow.
However, when I started using Linux, I was trying something well outside of my experience and knowledge: I was using it as a desktop OS.
Needless to say, I spent a lot of time searching the internet every time I had a problem or a question. In all that searching, I came to find one particular locale that always seemed to have the answers I was looking for.
It was called (and still is) LinuxQuestions.org. LQ is a massive forum, with subforums for the more popular distributions, and (in my experience) a very friendly, welcoming atmosphere for Linux users of all experience levels.
I know that in the fend-for-yourself world of Linux and open source software it can be kind of lonely out in the cold when you just CAN’T get whatever that is you’re working on to just WORK, damn it!
Do what I do. I go to LinuxQuestions.org and use their search page, and 9 times out of 10 I find what I’m looking for without even having to post my question.
So I think it’s worth giving the community at LQ some love, because they have been an invaluable resource for me in my years of using Linux at my primary desktop operating system, and I’m sure they can be for you too.

Oh yeah. Whenever I go Googling for something, most of the time the LQ result has the answer. And easily 9/10 Slack related questions I end up there for the solution. LQ is great.
