Community forums
Independent forums, Discourse boards and product communities are usually hosted by the company or project itself. Threads are indexed and long-lived, which makes them the best place to search before asking, and answers often come from the maintainers.
Community forums on this page are grouped by what they are about, so you can jump straight to the corner of forums you care about.
