LinuxQuestions.org - Must read topics?

Hi everyone. I already have two Linux Mint running and I'm feeling much confortable than with the other OSs. It is more friendly, manageable and transparent. I started to trust more Linux then the other commercial OSs. I can start planning better for my projects even though I still need Windows and Mac for some of them. Maybe until I start integrating them with new application if I find the way to replace them totally i.e. FileMaker Pro or LightRoom plus what ever there is there for video production. i have several projects for reporting, editing news and multimedia. I'm planning to run and know Drupal. That's my number one priority and knowing MySQL I see it as a water wall like the perfect storm coming, followed by photography projects. So I think that I will be searching for answer and making questions often. If someone can assist me with some must read topics related to this matters I will appreciate it. I have literally no budget. Honestely, I'm broke. And I have to emerge one way or another. I owe it to my wife for her support. Again thank you.
