[Mediawiki-l] AuthorRestriction Extension

[Getzke, John]

I know this is a touchy subject for some, but has anyone had luck with
this restriction Extension:
http://www.mediawiki.org/wiki/Extension:AuthorRestriction
<http://www.mediawiki.org/wiki/Extension:AuthorRestriction>  ?
 
I can see that it blocks users from reading pages, but does it also
block users from writing as well?  If there are any positive reviews for
this extension I would like to hear it, or even better... bad reveiws.
 
Thanks,
