We welcome comments from people with all kinds of mathematical backgrounds and levels of expertise; my requests are that the discussions are kept constructive, polite, and at least tangentially relevant to the topic at hand. Comments which are spam, self-promoting, off-topic, or otherwise not fulfilling the above requests will be summarily deleted; repeated offenders in this regard may be subject to blocking.

### Some technical remarks

This site has the ability to insert $\LaTeX$ math code into both posts and comments, e.g. $\int_{-\infty}^{+\infty}e^{-\pi x^2}dx=1$, math text rended by MathJax. The format for this is $Your-LaTeX-code$.  Note that double dollar signs  create LaTeX displays.
