[Mediawiki-l] Permissions based on sections

[GT4NE1]

Hi all,

I think I already know the answer to this, but I thought I would run
it by some people with more expierience with Mediawiki than I.

I want to create a wiki where I can create different sections that
different groups will use and assign permissions for each of the
groups.

Think departments in a company and creating different department
groups and not allow people outside of that department group to see
that department section.
