If you write in Hebrew, you should wrap your text with a right-to-left `div` to give it the right direction.

To do this, simply write [[div style="direction:rtl;"]] before the text and [[/div]] after (each on a separate line!).

This is especially important if you mix Hebrew and English, as the following example shows.

Without a div |

If you want to include math in your post, and know *some* TeX, you can use it in your posts. This may not be necessary just to write x^{2}, but can make your text more readable when you want to state that $S \Rightarrow \epsilon$ or compute

To use inline TeX, write it between [[$ and $]] (e.g., [[$\frac{1}{\sqrt{2}}$]] gives $\frac{1}{\sqrt{2}}$).

To use an equation on a whole line, write it between [[math]] and [[/math]].
