[Mediawiki-l] In Other Languages

[Frederich, Eric P21322]

Hello everyone.  I am trying to figure out how to get that side bar "in
other languages" working on my Wiki site.
In a page called sandbox, I put at the bottom a link [[de:Sandbox]] but
it just stayed as a link on the bottom of the page instead of making its
way into a new sidebar on the left.
What do I have to do to get this working?  Is it just a matter of
creating the sidebar?  If so, how do I do that.
Any help is appreciated, I tried looking around but couldn't find much
of anything.

Thanks,
