[Mediawiki-l] Adding further nav sidebars without getting "$1" in title?

[Ken McDonald]

My understanding is that I should be able to add further navigation 
sidebars (separate from the default nav sidebar) by putting more 
top-level outline elements in the "MediaWiki:SideBar" page. This works, 
but it also give me a "$1" in the sidebar. Presumably I'm not including 
data that, at some level, PHP expects, can anyone tell me what I'm doing 
wrong?

Thanks,
Ken
