{errors} is for questions regarding or including compilation or similar errors.

Error messages which mostly show (La)TeX code should be marked as a code block (indent with 4 spaces or the {} button), not as a quotation (>).

Error messages which mostly show file paths and no code, like File not found or similar errors, should be placed between <pre> and </pre> HTML tags to avoid wrong syntax highlighting. Otherwise in e.g. c:\localtexmf\latex the two directories would be highlighted as macros because of the preceding backslashes \.
