Currently a user can select an interface language for their skin to display. 
However it is not possible to refer to messages in the user's language in-page.  

For example if one wishes to make a reference to name of a site's "Recent 
changes", one can insert {{MediaWiki:Recentchanges}} into the document and it will 
display the "Recent changes" message even if the text is changed to something else. 
 However this only works in the wiki's base language: even if the user changes 
their interface language away from English, {{MediaWiki:Recentchanges}} will still 
display the English text, not the chosen language, when preferably it should show 
the latter.
