Some new features

You can now give yourself a nickname in your settings. This allows you to set a display name for yourself that includes a space – a nice feature for those of us who previously had to use a hyphen or camelcase for our multi-word names. 🙂
Writing things like [math]\frac{n!}{k!(n-k)!} = \binom{n}{k}[/math] or [math]{\displaystyle \sum _{n=0}^{\infty }{\frac {f^{(n)}(a)}{n!}}(x-a)^{n}}[/math] is now a possibility with the [math] TeX tool! I don’t know why you’d need it, but hey, it’s cool.
