For help with LaTeX questions, users can turn to several resources, including the Physics Forums and the TeX Stack Exchange. The Physics Forums has a dedicated Math and Science Software forum that covers LaTeX topics. For basic inquiries, users are encouraged to check existing resources or post in the relevant subforum on Physics Forums. For more complex questions, the TeX Stack Exchange is recommended, as it features experts who can provide detailed assistance. Engaging with these platforms can significantly enhance understanding and problem-solving in LaTeX.
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).
