Help:Interwiki linking
From MediaWiki
Interwiki linking (linking to an article on Wikipedia, a Wikia, or other wiki in general) is medium-complicated, but not that hard to learn.
Linking to Wikipedia
To link to the Wikipedia article "Trains" type; [[Wikipedia:Trains]]
Linking to Wikias
There are two kinds of wikia-link markup. To link to the article "Supergate" on the "Stargate" wikia, use this format; [[Wikia:sgcommand:Supergate]]
The other format, used by many older wikis, includes a 'wikia:c:' prefix, a holdover from Wikia's 'Wikicities' days. To link to the article "Shipwreck" on the "Gijoe" wikia, use this format; [[wikia:c:gijoe:Shipwreck]]:
Several sites on Wikia, such as Memory Alpha, have their own domain and can be linked to using a similar pattern to non-Wikia wiki: [[MemoryAlpha:James T. Kirk]]:
