I'm quite new to MediaWiki and I have a question, I'm working on a wikia who's kinda a translation of another, where I can set that when i call en:something goes to the page something of the english wikia?
Thanks in advance
What you're talking about is something called "interlanguage links" (Help:Interlanguage links).
Before you can use interlanguage links, there's a one-time connection that has to happen to put the wikis in each other's interwiki map. You can request that at Community Central:Interlanguage link requests
What do you think?
