[Mediawiki-l] Restricting user rights

[Daniel Mendes]

Hello everyone,
I'm looking to create a wiki in which two sets of people have different
rights to the pages.  For example, one group has rights to create and modify
the original content but a second group is only allowed to write a summary
about the original content.  Is this possible in mediawiki?
