C++ FAQ Celebrating Twenty-One Years of the C++ FAQ!!!
(Click here for a personal note from Marshall Cline.)
Section 5:
[5.9] Which newsgroup should I post my questions?

Only post to comp.lang.c++ if your question is about the C++ language itself. For example, C++ code design, syntax, style, rules, bugs, etc. Ultimately this means your question must be answerable by looking into the C++ language definition as determined by the ISO/ANSI C++ Standard document, and by planned extensions and adjustments. Operating-specific questions (e.g., about Windows NT / 95 / 3.x, UNIX, etc.) should go to an operating-system-specific newsgroup (see below), not to comp.lang.c++.

Here are some other potentially relevant newsgroups:

  • comp.lang.c++.moderated
  • comp.object
    • Mostly OO design issues, with less emphasis on OO programming
    • That group's FAQ contains an excellent introduction to OO along with an overview of OO terms and concepts

Usenet isn't the only place that has forums to answer your questions. You might also try Techi-Warehouse, among others. Please don't email me asking to add others; I don't have time (or the interest!) to make this an exhaustive list of forums.
