There’s quite a lot of information buried in this forum that you can read and learn from. Just search key words you’re interested in and read through the forums. That is how I gained most of the knowledge that I have (which still pales in comparison to many of these much smarter guys)
One of my favorite threads is stickied somewhere in here, I’ll have to find it. But it I really like to reference that thread when I have questions about the basics.
EDIT: found that thread. Don’t read too much into the title of it, this isn’t to insult your intelligence. There is a lot of good beginning and intermediate level knowledge in Furious George’s posts.
