[pmwiki-users] create certain pages in shared store by default

[Bronwyn Boltwood]

I've created a shared writable directory (exalted.d) for a wikifarm. 
I need all pages created in certain groups to be stored in exalted.d
instead of wiki.d, and it has to work when clicking a create page link
from pages in groups stored in wiki.d.

What's the best way to do this?
