It's changed a lot over the years. There were forums I belonged to early on, but most are gone these days. Typically, if I have a question about something particular these days, I Google it, and usually run into a YouTube video, or a random link (a lot of those end up being Reddit).
I don't release music (although I do consider from time to time). I mostly just enjoy the process, and listening back to older work.

I think you should!
Not that my opinion counts for anything, I need to take my own advice. But my guitar teacher said something recently that really hit me - "You don't need to wait 20 years until you're the perfect player before you put music out into the world."
This was a big part of what made me feel confident enough to publish the solo video I linked in my other comment, and I've got some other stuff in the works too. I am trying (to some very small success so far) to be a little less fearful of looking stupid or putting something half baked out into the world.
Music is for everyone! Share it. (Or ignore this advice, that's ok too, don't let me tell you what to do ;)
