The discussion centers around the functionality of the \leftflush command on the site, with participants clarifying that there is no such command; the correct command is \flushleft. It is noted that while MathJax primarily supports LaTeX for typesetting formulas rather than text, users seeking to align text should consider using the left align button available during posting. Concerns are raised about the potential ineffectiveness of the \leftflush command even if it were accepted by MathJax.
