wikipedia-ish version, restricting new registration

A table of contents is created automatically once there are a few headings, placed before the first heading. Or you can add __TOC__ in the spot where you want a table contents and it will be put there.
Footnote references are created with the Cite extension. Syntax is explained on that page.
To prevent account creation by unregistered users use:
```
$wgGroupPermissions['*']['createaccount'] = false;
```
Adminstrators will still be able to create accounts for users. ConfirmAccount might also be useful if you want people to be able to request accounts.
To disable page creation for unregistered users use:
```
$wgGroupPermissions['*']['createpage'] = false;
```
To disable editing for unregistered users use:
```
$wgGroupPermissions['*']['edit'] = false;
```

thanks a lot!
