The discussion revolves around finding resources and forums for assistance with LaTeX questions. Participants explore various platforms where LaTeX-related inquiries can be posted, including specific sections within Physics Forums and external websites.
Participants generally agree on the existence of multiple platforms for LaTeX assistance, but there is no consensus on a singular best resource, as preferences vary based on the complexity of the questions.
Some participants reference specific threads and forums without providing detailed descriptions of their content or effectiveness, leaving the evaluation of these resources unresolved.
If you're looking for just an introduction to how to write basic math in LaTeX, there are many resources available but the https://www.physicsforums.com/showthread.php?t=386951 is probably the most convenient if you're already on PF. If you want to ask a basic question like, say, how to create a parenthesized matrix, I'd advise you to look at your favorite reference because it's probably in thereAxiomOfChoice said:
but if that doesn't help you, then I suppose you could ask a question like that in the PF subforum that jtbell mentioned. But if it's a more subtle, advanced question, the *TeX Stack Exchange site (tex.stackexchange.com) is probably the best place to go of the three mentioned so far. There are quite a few real TeX/LaTeX experts there who can answer even pretty arcane questions, but they will expect you to have done your homework before asking (i.e. check your resources, search the web, and really put some thought into formulating your question well).
