Questions tagged [message]

For questions regarding Facebook messages, JavaScript messages, mobile messages (Android, iOS, windows-phone), etc. Not for use for error messages. Include additional tags to indicate messaging platform, programming language, etc.

Questions about sending and receiving messages of any kind. As this tag is vague, use a more specific tag instead if possible. For example, most questions about Facebook messages should have the tag for the programming language, , and possibly a tag for the API or framework you're using. If your question is about a , an , a window, a , an , … then use the appropriate tag instead. Do not use this tag (or any tag) to indicate that you tried something and got an error message.
