This is just a private sandbox I'm using to take notes
A link in external link style can be of the forms:
| target | http://meta.wikimedia.org/ is rendered as http://meta.wikimedia.org/ |
| [ target label ] | with a blank space in between: [http://meta.wikimedia.org/ wikimedia] gives wikimedia (see also Help:Piped link) |
| [ target ] | these are automatically labelled with serial numbers 1, 2, 3, ...: [http://meta.wikimedia.org/] gives [1] |
Where target is a URL which can start with "http://" or "ftp://";
"file://" does not work by default. If enabled it only works in MSIE. To enable it, add a $wgUrlProtocols entry to LocalSettings.php; see the $wgUrlProtocols in DefaultSettings.php for example.
