You can easily create links to other wiki sites for which we have created inter-wiki shortcuts.
For example, the prefix mediawikiwiki: in a wiki link makes it a link to the MediaWiki site rather than this wiki. A simple example of this is:
[[mediawikiwiki:Help:Editing pages|Editing pages]]
which creates the link "Editing pages".
Use the prefix :wikipedia: to create a link to the Wikipedia, as in
[[wikipedia:QuarkNet|QuarkNet]]
which creates the link "QuarkNet"
