## Editing pages

The most detailed explanation is given on the corresponding page of MediaWiki. In MolWiki the most important principles are:

- Please follow the general practice of good scientific writing.
- Prove your statements by including references to peer reviewed journals.
- Use preview functionality as much as possible! Try not to save changes just for testing purposes.

### Source code

To publish source code with highlighted syntax use code tags with indication of the language type:

<code language> Your source code goes here... </code>

The following example is for Fortran:

<code fortran> C A Simple program program hello print *, "Hello World!" end program hello </code>

The result is
```
C A Simple program
```

program hello
print *, "Hello World!"
end program hello

```
```

### Mathematical formulae

You can include formulae by using

<math></math>

tags and LaTeX syntax. The example

<math> \operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}} </math>

produces the following output:

[math]
\operatorname{erfc}(x) =
\frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
\frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
[/math]

You can click on the formula to enlarge it.

### Molecular structures

MolWiki.org has a Jmol extension, which can be used to show molecular structures interactively. To create a link to a molecular structure upload a XYZ file and use the jmolFile tag:

<jmolFile text="An example of molecular structure">C26NH28.xyz</jmolFile>

The example produces the following link:

An example of molecular structure

## Participating in discussion

Each article has a dedicated discussion page where you can ask questions, find more information on the topic and talk to other people. More information about discussion pages is on MediaWiki site.
