[Mediawiki-l] Sister project vs. two namespaces in bilingual wiki

[Alfonso Muñoz-Pomer Fuentes]

Hi, I installed MediaWiki a week ago and I'm tweaking it now just before
starting to populate it with content.

My issue is that I'm doing a bilingual Japanese-English wiki, where each
page has its correspondent one in the other language (which would be
only a translation). I've read all I've been able to find about having
two namespaces or doing a sister project, but as it's extremely
convenient to have only one user database I've opted for creating two
namespaces. The problem is that the title of each page is now
"English:Pagetitle" or "Japanese:Pagetitle". Is it possible to remove
the namespace and colon there?

Has anybody run into the same problem of setting a multilingual wiki
that made mandatory the use of only one user database? Is it possible to
share the two user tables across two different wikis?

Thanks in advance...

Alfonso
