[Mediawiki-l] Moving wiki down one level; setting up two wiki's

[Tim Ware]

I want to move my wiki, now at the top level of the htdocs, down one  
level into a subdirectory. Any pitfalls here that I should be aware of?

This wiki explores one particular novel of an author's, and  I want  
to have another directory for another of his novels. Should I do a  
separate install of MW for the additional novel, or just a separate  
database?

Ideally, I'd like to have a search where one could search either  
novel or both.

I hope I'm being clear here. Thanks!

Tim
