[Mediawiki-l] Site name questions

[Philip Beach]

I'd like my wiki name, "My Wiki," to be in the title bar, but I'd like the
namespace to be "mWiki".  On my PC version, I've set $wgSitename to be
"mWiki", and I read somewhere on the MediaWiki site that you can have the
name in the title bar be different.  Alternatively, I think you may be able
to have $wgSitename set to "My Wiki" and the namespace be something
different.  How can I go about doing this?

Thanks,

Phil
