I think my question would be off topic on TeX - LaTeX but I'm not sure where to ask it. Where can I ask a question like this:
I've used LaTeX for several years, but just with basic functionality: writing papers with sections, figures, labels, bibliography, and the occasional table. The problem is that when things get more complicated I have no idea what to do, and I usually end up searching online for several hours to find a "solution", which is usually more like a hack that I don't really understand.
Are there books or tutorials that can help "intermediate users" like me?
