Wiki Permissions

[Jeff Sheltren <sheltren cs ucsb edu>]

I don't understand why there are no permissions set up for the Wiki.   
At this point, anyone can 'login' and edit the pages which is leaving  
all sorts of spam around.  It'd be nice to have real accounts which  
can be granted access to edit pages - people could mail their  
username to the list to get it added to the edit group.
